I updated Events Manager from 5.2.6 to 5.3.5 under WordPress 3.4.2, and some notification bubbles have appeared in the menu, like so:
I can't figure out why they're there. I trashed all of the recurring events (which were in the past anyway) and then permanently deleted them too. That hasn't got rid of the numbers.
I then upgraded to WordPress 3.5.1. The numbers remain.
What are they, and are they considered harmful?
