Reviewing your statistics, you do have a paid membership and also "include lab caches in your statistics" checked because a lab cache is displayed as one of your types under Hides tab.

If the problem persists and your Diverse Cacher badge keeps jumping a level, you might consider requesting Support to help figure out what is going on. Support can be reached via the orange button from the Dashboard.
