Admin bar is visible on the cached page

Hello,

I hhave two main pages. The second language main page gets cached with the admin bar. I cleaned all the cache and did not visit the page till it is done and cached. It still cashes with the admin bar. I tried to only delete the url cache and checked from incognito tab but it still shows the admin bar. It is very important to solve the problem as any visitor can see the admin name.

The page I need help with: [log in to see the link]
