It's not your center boxes that are "misbehaving"; what you see is the product listing page at the level of the (sub)category that directly holds the products. You cannot get the listing page in the parent category.
If you are concerned about customers not understanding that they have to click a subcat name to see the products, you can put some description and maybe an image in the subcategory definitions. That will better inform them as to the reason for the subcat divisions and why they may want to look at each one.
Mmmm... ok I see your issue. don't yet see what could be causing it. Will have to check on some things.
