On the Membership Trends Report under "Active Members," you do NOT show Active Members, you show "Active Bundles for levels with Bundles." Bundles include more than one Member so the count of Active Members is incorrect because it's a combination of Members and Bundles if you have levels with Bundles, which we do..

However, the Members Summary List shows both Members and Bundles, which is more informative and shows the correct number of Members.

Suggestion:
Change the Membership Trends Report to correctly show only "Active Members" (not Bundles) like the heading indicates. Or show both Members and Bundles like the Members Summary List.
