Problem with the Menu

Content: Hi,
I just installed xili after using polylang for years, because somehow polylang stopped working.
My website has 2 languages, english and chinese and my problem is that after installing xili and assigning the pages to each menu according to its language, even if the content of the pages is swithing from english to chinese, the menu bar on the top is always appearing in english, never showing the chinese menu.
Do you have any idea why this happens?
Thanks!
