Polylang language selector with flags

Hi,

I’m currently creating a multiple languages website with “Bridge” (Qode) theme. I installed “Polylang” as well as “Duplicate Page” plugin…to duplicate my pages… There are only 3 different pages on my site.

So, I assigned a language per page, created 3 different menus and assigned them the right location, I also created 3 different contact forms (the site is translated manually by the owner himself).

My problem is : when I am using the language selector with flags it won’t loaded the right menu…
For instance : I’m on a french page, I click on the english flag to switch language > it takes me to the english page BUT keeps the french menu -_- unless I reload it one more time manually.
The weirdest is that when I am using the dropdown selector everythings works perfectly. Of course I want to use the selector with the flags.

What can I do about that ?

I did not duplicated all my pictures, could it be a problem ?

Thank you so much!
