This is one of the most frequently asked questions in ResearchGate. Indeed, RG's algorithm for the identification of citations is far from being perfect. Very often it gives incomplete or wrong results. However, users are hardly able to do anything, but see this method developed by Andrejs Krauklis for improving the identification in your own publications: https://www.researchgate.net/post/Method_for_Improving_Recognition_of_Citations_References_on_ResearchGate. My experience is that it works sometimes, but not always. And you have to use it before you upload your publication.

Dear luis alberto mendez-rosado ,

You refer to Jiménez, P. A. D. V., Hernández, B. D. C. V., Rosado, L. A. M., Torres, M. S., & Martínez, A. B. (2022). Diagnóstico de familia portadora de una translocación entre los cromosomas 5 y 15. Revista Cubana de Genética Comunitaria, 14(1).

As far as I can see this is an open access paper. I would upload the pdf file (see enclosed file) and see if the RG algorithm recognize more references. Otherwise, you can try the Andrejs Krauklis suggestion made by Wolfgang R. Dick since the paper is authored by you.

Best regards.
