Adding New Access Level is Failing

Hello,

I am running the most recent version of Membership 2.1.2 with a WP Multisite installation 3.2.1.

I am trying to add access levels.

Currently I go to the Access Levels menu and click Add New. After entering a title for my level and then selecting my options (currently only Category in the Positive rules), I click Add to create the level. Once this is complete I get the "Membership Level Added" message but no level is actually created.

I checked to make sure that I just hadn't forgotten to activate them, but nothing is ever created.
