Subcategories not working sometimes

Hi,

i have created a shop using your theme and I’m having a problem with some subcategories not working and showing error 404.

I have “Category 1” and “Subcategory 1/2/3/4” – they are working fine.

Then I have “Category 2” and “Subcategory 1/2/3/4” – these are not working. They are created in the Categories settings, they can be added to the product, they can be added to menus, but when I click on them, I get error 404 (the main category works fine).

Same goes for Category 3 etc.

Also I have the “Page title show categories” option enabled and I can see subcategories from working Category 1, but it does not show Subcategories from the problematic Category 2.
