Membership and Custom Taxonomy

Encountered an issue with Membership Pro and custom taxonomies...while custom post types seem to fall into a positive type by default, taxonomies fall into the negative. Not sure how since neither show up in the DB... but that's why I'm here.

I did come across a post of a similar nature here:

However, while it explains a fair bit it is a little bit cryptic when it comes to adding Taxonomies to Level administration. Ultimately I would be happy to just give my taxonomy a positive rule and get this project out of the way.

Anyone have a thought?
