herka on "Categories missing subcategories?"

Since last update to 3.8. my categories are missing their subcategories.

Funny thing is i dont see the subcategories as before in Posts->Categories list, but i see them when i want to make a new category and i see them when im writing a new post. also i can assign a post in a subcategory.

Also when i open a category in browser i can only see categories that dont have a subcategory - if i open a category that has a subcategory i get a view like there is no posts in that category.

Hope this can be solved somehow...

Thanks for all the help in advance.
