category view not working

WordPress 3.8 wp-ecommerce version 3.8.12.1 (free version)

On my products page it displays all of the parts we offer in numeric order by part number. We have the categories arranged according to the table of contents in our owners manual on the side bar along with the shopping cart widget.

When we click on a category in the sidebar the page changes and only shows a compact display of the part description at the top of the page. No photo, no add to cart button, no qty display – nothing.

We recently upgraded from an old previous version and it worked under that version. Please advise.
