ABNT6023 Latex Bibliographic References

Question

I have a question regarding Latex, more specifically in ABNT 6023:2018 standards. I would like to know how I can change the year of a reference in the Bibtex archive.

Example:

@mastersthesis{alvesjoao2019,
  title={Um modelo preditivo de cotação de ações de empresas estatais brasileiras utilizando redes neurais artificiais no ambiente MATLAB},
  address={Uberlândia},
  author={ALVES, João Victor da Silva},
  year={2019},
  school={Universidade Federal de Uberlândia},
  type={Mestrado em Gestão Organizacional}
}

You’ll get the exit:

ALVES, J. V. d. S.A predictive model of stock prices of Brazilian state-owned companies using artificial neural networks in the MATLAB environment. 2019. Dissertation (Master in Organizational Management) - Federal University of Uberlândia, Uberlândia, 2019.

As you can see there are two years of 2019, but how can I change the second year. Although this file actually has two 2019, there are other references that have different dates, how can I change this?
