Permalinks for Product Pictures and Titles not the same

The permalinks for my products in my multisite store are not the same for the product images and the product title link. Some of them work (open a product page when clicked) and some of them do not work. The ones that have the title of the item directly after our site's URL do not work (ex: artistsalley.net/hat). The others seem to all work (although they do not match each other). Is there a way to fix this? I'm sure this is a result of the MP update (many had variables that didn't have images assigned to them). I went in and manually assigned the variables images, but now this problem has crept up. Can you please advise? http://www.artistsalley.net
