WP-Ecommerce url structure issue

$30 - $100

Project Description:
We have updated our wordpress to the latest version as well as wp-ecommerce the link structure was /products/products-page followed by the catagory and then the product. After the update it changed to /products/-page followed by the catagory and product. we cannot figure out why. i have it set to custom right now and all i put in is -page and now both structures will load the same product so obviously this is not a good solution but at least i am not getting 404's. The permalink setting was the same before and after the update. It is possible someone custom coded products-page in there in the old version. im not sure. Does anyone know how to fix this?

i forgot to mention when set to the same permalink structure in the updated version it removed producst-page completely and just showed /products/ . when we added the products-page into the php it shows back there but drops the products part for some reason.
