Chinese menu navigation goes back to English page of the menu item

[raeuske]

I have this website https://chineserestaurantawards.com with English and Chinese language (https://zh.chineserestaurantawards.com/ )

Not sure since when, on the Chinese language page - the navigation - when I click on some menu items (internal links in this wordpress) - they all goes to English page of that menu items.

For example
It's supposed to go https://zh.chineserestaurantawards.com/about-cra/ but the link is and will go to https://chineserestaurantawards.com/about-cra/ (See my screen cap - the lower left corner showing the link)

Not sure why .. hope someone can help
