Return inside the control does not send to the right maproute

Question

Good afternoon, I’m trying to use maproute to control editing and inserting data in the table, currently my routeConfig is like this:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        /*Sub Categoria*/
        routes.MapRouteWithName(
             name: "Editar Subcategoria", // Route name
             url: "CanaisDigitais/Subcategoria/Edit/{id}/{idp}",
             defaults: new { controller = "CanaisDigitais", action = "EditSub", id = UrlParameter.Optional, idp = UrlParameter.Optional }
         );
        routes.MapRouteWithName(
              name: "Deletar Subcategoria", // Route name
              url: "CanaisDigitais/Subcategoria/Delete/{id}/{idp}",
              defaults: new { controller = "CanaisDigitais", action = "DeleteSub", id = UrlParameter.Optional, idp = UrlParameter.Optional }
          );
        routes.MapRouteWithName(
            name: "Subcategoria", // Route name
            url: "CanaisDigitais/Subcategoria/{id}",
            defaults: new { controller = "CanaisDigitais", action = "Subcategorias", id = UrlParameter.Optional }
        );

        /********************************************************************************************************/
        /*Conteudo*/
        routes.MapRoute(
            name: "Conteudo", // Route name
            url: "CanaisDigitais/Subcategoria/Conteudo/{id}",
            defaults: new { controller = "CanaisDigitais", action = "Conteudo", id = UrlParameter.Optional }
        );
        routes.MapRoute(
             name: "Editar Conteudo", // Route name
             url: "CanaisDigitais/Subcategoria/Conteudo/Edit/{id}/{idp}",
             defaults: new { controller = "CanaisDigitais", action = "EditCont", id = UrlParameter.Optional, idp = UrlParameter.Optional }
         );
        routes.MapRoute(
              name: "Deletar Conteudo", // Route name
              url: "CanaisDigitais/Subcategoria/Conteudo/Delete/{id}/{idp}",
              defaults: new { controller = "CanaisDigitais", action = "DeleteCont", id = UrlParameter.Optional, idp = UrlParameter.Optional }
          );
        /********************************************************************************************************************/
        /*Rotiamento do fórum*/
        routes.MapRoute(
            name: "Topico", // Route name
            url: "Forum/Topicos/{id}",
            defaults: new { controller = "Forum", action = "IndexTopicos", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Editar Topico", // Route name
            url: "Forum/Topicos/Edit/{id}/{idp}",
            defaults: new { controller = "Forum", action = "EditTopicos", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar Topico", // Route name
            url: "Forum/Topicos/Delete/{id}/{idp}",
            defaults: new { controller = "Forum", action = "DeleteTopicos", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        /*********************************************************************************************************/
        routes.MapRoute(
            name: "Posts", // Route name
            url: "Forum/Topicos/Posts/{id}",
            defaults: new { controller = "Forum", action = "IndexPosts", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Editar Posts", // Route name
            url: "Forum/Topicos/Posts/Edit/{id}/{idp}",
            defaults: new { controller = "Forum", action = "EditPosts", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar Posts", // Route name
            url: "Forum/Topicos/Posts/Delete/{id}/{idp}",
            defaults: new { controller = "Forum", action = "DeletePosts", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        /*********************************************************************************************************/
        /*
         * Roteamento dos tipos da a genda
         */
        routes.MapRoute(
           name: "Agenda tipos", // Route name
           url: "Agenda/Tipos/{id}",
           defaults: new { controller = "Agenda", action = "IndexTipos", id = UrlParameter.Optional }
       );
        routes.MapRoute(
            name: "Editar Agenda tipos", // Route name
            url: "Agenda/Tipos/Edit/{id}",
            defaults: new { controller = "Agenda", action = "EditTipos", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar agenda tipos", // Route name
            url: "Agenda/Tipos/Delete/{id}",
            defaults: new { controller = "Agenda", action = "DeleteTipos", id = UrlParameter.Optional }
        );
        /*******************************************************************************************************/
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

    }

But when I access http://localhost/Canaisdigital/Subcategory/Edit/1/10 and edit some value that gives an invalid status in the template and goes back to the view it directs me to the url http://localhost/Canaisdigital/Editsub

This is the code I use in the Controlle to return when the model is invalid:

return View("Subcategoria/Edit", Modelo)

Can any good soul point me in the wrong direction? Note: Use MVC 4 and dotnet 4.0 can not update either.
