Categories and subcategories not displaying properly

[canemasters]

I'm making a new site and trying to fix this problem. Check out:

http://www.dashtop.com/shop/trucks-c-4.html

You'll notice that the categories only display 2 wide, even though I have it set to 3 in the admin. If I set it to 2 wide, it goes to 1 wide.... I'm not sure what's going on.

And if you click on chevy / gmc in the trucks category, it does it there as well.

I've played with the page width in the css, the subcategory image size, the side boxes size... nothing will fix this.

Please help!

Thank you.
