villagers do not change professions

The villagers don't change professions when I remove their work table, without me having even purchased any item from them, I don't believe it's because of the trade adjustment, as it is an optional option and is not activated in my world.

A villager got the farmer skin, but when I go to trade with him, no option or button appears

Sorry for the horrible English, I'm Brazilian and I'm using the translator
