Lingotek menu translation

Hi,

I’m trying to fix a problem within a multi language site that’s finished.
Website is here.

So when I want to choose another language (with the flag) the menu doesn’t change in the language I’ve chosen.

So in the menu section, I got 3 different menus, one for each language. But still nothing helps, I’ve search everywhere where the problem could be, but can’t find it.

Hopefully can someone help me to fix it please.

Thanks!
