WooCommerce Primary Sidebar

I just installed Catch Base Pro in my test environment, and I am also testing WooCommerce there. I have a question about how the WooCommerce Primary Sidebar is working. I don't know if I should take this up with you or with WooCommerce, but I thought I would start here. I have two widgets in the sidebar: WooCommerce Product Categories and WooCommmerce Cart. When I am in the "store," the sidebar works fine. When I go to the cart or checkout pages, the cart widget disappears from the sidebar, which is fine, but I can't get rid of the Product Categories widget. I have tried setting the Cart and Checkout pages to a "No Sidebar (Full width)" layout, but that doesn't seem to make any difference. I have also played around with the default WooCommerce layout, but that doesn't seem to make any difference either. Any ideas?
