SOMETHING GOT MESSED UP IN A RECENT MARKETPRESS UPDATE

Product categories used to work great and look beautiful. But in a recent plugin update, something got messed up. It now seems to ignore my template layout styles, and instead of listing the products by title, it displays them all as "Product Category: "category name". For example for the Bookmarks category, each item is now titled "Product Category: Bookmarks". What used to be a nice layout of products by category now looks sloppy. For an example, please see:

Thanks for your help!
