How do I get CustomPress custom taxonomies to show up on MarketPress products?

I have created my custom taxonomies, ‘Specialty’ and ‘Type’ and have exported them from my network CustomPress settings and imported them into one of my sites, but when I go to create a new product, these taxonomies don’t show up. I opened up ‘screen options’ to see if I needed to enable the panes for viewing, and found that they weren’t listed there either. What am I missing?
