Edit pages different languages

Hello, I don’t know what’s going on.
My site is in multilingual, Portuguese and English.
One page for Portuguese and one for English (servicos(PT) and services(en)).
When I try to edit the page in PT (edit in colibri) it shows the page in Portuguese (in the background) but then when it’s in edit mode it changes to English. If you choose the page in EN, you also load the page in English.
I’ve already deleted the pages and created them again, but the same thing happens.
When accessing the site shows the correct pages and if you click on the link, inside the editor (permanlink) also shows the correct page.

Thanks
