Background of the issue:
I am trying to resolve an issue where a menu item is not showing in the German translation but is present in the English menu on the site 隐藏链接. The item in question is the industrial water treatment page, or in German, Industriewasseraufbereitung.
Symptoms:
The menu item is marked as invalid in the German pages.
Questions:
Is it easy to re-add the page to the menu?
Why would the menu item be marked as invalid in the German pages?
