Why are the number of subscribers associated with my List incorrect on the Lists page?
We improved the speed on the Lists page so realms with many lists and subscribers will load the page more quickly. Occasionally an older method to subscribe or unsubscribe may not update the list count as expected. At this time, we have resolved most of these hidden issues, but it may still exist in older versions.
If you notice the List Counts are off, click the number in the Subscribers column to recalculate the subscribers and update the number.
