Display Null Variables in a Modal

Question

Guys I’m having the following problem.

I had to create an audit page of my system, where it displays the edits that were made in a certain form.

When a form is first filled in, it shows all the form variables, as you can see in the picture below.

when the same form is edited, it displays the following screen.

As you can see, on this second screen, it does not display all variables.

and my problem is this, I need that on this second screen, it exits all variables.

this modal is displaying only the variables that have been edited, I need it to display everything, even if there is no data in the field as shown in the photo above.

my JS

$(document).ready(function () {
    $('[name="btn_detalhes"]').click(function () {
        var altaUtiId = $(this).attr('id');
        var patientId = $(this).attr('data-content');
        $.ajax({
            method: 'POST',
            url: '/Formulario/AltaUTI/VerificaDiff',
            data: { 'PatientId': patientId, 'AltaUtiId': altaUtiId },
            success: function (response) {
                var t1 = response[0];
                var t2 = response[1];
                var registro = response[2];
                if (t1.length > 0 || t2.length > 0) {
                    $('#msgLoading').fadeIn(0);
                    $('.modal.Detalhes').modal({
                        closable: false,
                        blurring: true,
                    }).modal('show');
                    for (var i = 0; i < t1.length; i++) {
                        $('#trInser1').append('<p> ' + t1[i] + ' </p>');
                        if (t2.length > 0) {
                            $('#tdInser2').append('<p> ' + t2[i] + ' </p>');
                            $('#tdInser2').removeClass('display-none');
                            $('#colAtual').removeClass('display-none');
                            $('#colAtual').fadeIn();
                            $('#tdInser2').fadeIn();
                        }
                        else {
                            if (registro.length > 0)
                                $('#colAlterado').text('Usuário alterado');
                            else
                                $('#colAlterado').text('Usuário atual');

                            $('#tdInser2').addClass('display-none');
                            $('#colAtual').addClass('display-none');
                        }

                    }
                    $('#msgLoading').fadeOut(0);
                } else {
                    notif({
                        'type': 'error',
                        'msg': 'Não foi encontrado modificações no formulário!',
                        'position': 'center'
                    });
                }
            },
            error: function (response) {
                notif({
                    'type': 'error',

                });
            }
        })

    $('.btn_ok').click(function () {
        $("p").remove();
        $("#colAtual").css({ display: "none" });
        $("#tdInser2").css({ display: "none" });
