Language switch

Hi Maxime, I just installed it recently and it works great, I just have an issue:

when changing page from the navigation menu it keeps the selected language, but when I click on a basket button or other buttons, like footer, and open the page it always brings me back to the default language and doesn’t keep the selected one. Is there something I missed in the settings?

Is there any way to leave on the navigation menu only one button for both languages where only the non selected one is visible?

Thank you for the great work!
