[SOLVED]Show products of same category bug?

[Rakward]

I noticed that the block of "Products in the same category" only displays when clicking on a product found through the category navigation pages. Even when clicking on a product of that same category, the block disapperas ...

Is this is a bug or is it supposed to happen this way?

Edit:
------
Just noticed it only seems to happen to my own products in my own categorys, not the default prestashop modules/categorys.

I only created a Television category with 2 subcategorys and placed some products into it. What might cause this problem?

Edit2:
--------
Nevermind, had to choose default category
