Craftycart with e-commerce needs one last tweak but I'm stuck!

I’m trying to set up a little website and think I’ve done okay so far but appear to be completely and utterly stuck with one thing now. I’m using the wp e commerce with craftycart. Everything is fine apart from I have my products in categories and when you click on a category you get a list of all the products in it with photos (which is great) but right at the top you get a repeated heading of one of the products with a category list under it. I have no idea why this is happening or what to do about it.

Can anyone offer any advice? Thanks in advance.
