Weird Layout of Store Page vs. Products Page

Just bought Quick2Cart and I am configuring it (havent made any code customizations yet) and for whatever reason, the layout for the store page (https://www.popuprepublic.com/component/quick2cart/jeremysstore/store.html?Itemid=9329) is different than that of the products page https://www.popuprepublic.com/component/quick2cart/productpage.html?view=productpage&layout=default&item_id=1&Itemid=9329. The products page looks fine and works well within my site's template, so I don't think it's a template issue.

Has anyone encountered this problem before? Any ideas?
