Everything you said was right !
Thank you for taking the time to understand what i said.
All my taxonomies are gone with the process and i have to recreate them, but it work so everything’s fine
Thanks a lot
Thanks for your answer annd sorry for my english.
I’am talking about the filter section wich permit to display project with the specific categorie selected like on this example https://theme-one.com/the-grid/oslo/ .
The filter section wich i called menu is handled by the plugin The grid (https://theme-one.com/the-grid/) and is working perfectly fine if i desactivate Polylang.
I hope i managed to clarify.

Juste to clarify, when i Say menu, i talk about the filter menu.
