home url with problem

Hi guys, I’m having a problem with the main page of my site, I can’t make it stay .com.br which is the right way, it always stays .com.br/pt/ and when I want it to stay on the page in Spanish I would like it to stay only .com.br/es-es/ and not es/esp/ and in Portuguese I would like it to be .com.br/pt-br/ and not pt/br/ my website is https://stampdesign.com.br/

can anyone help?
