Not saving

I upgraded to the premium version.
The settings for custom images works for the main menu, however I would like to use it to customize product pages.
The product pages shows in the list, however when I add and image, and then press ‘save’ it doesn’t save that item. It comes back up as not being set. Post type product.
I have set the Taxonomy – product_cat but they save, but they do not show on the page.
