Problem:
I have a category page called Portfolio in English language. I've translated the category to the slug portfolio-pt, but if I go tho the Menu and choose in Portuguese and then click in portfolio (PT) it goes back to portfolio in English. Solution:
I checked that this issue was being caused due to this Yoast setting being disabled:
Yoast -> Settings -> Categories -> Additional settings -> Show the categories prefix in the slug
To fix it I went to WPML -> Settings -> Taxonomies Translation -> Categories (category) -> Set different slugs in different languages for Categories and removed the Portuguese translation in there.
