I just realized that the leaderboard of the space I am managing (Life Sciences) went blank. I saw a similar behavior in other spaces (e.g. Business ByDesign), where the leader ahs like 7 points. It looks like only the points from the current year are counted and not the last 12 months. I checked the widget settings in my space and the settings are "Year" for the Leaderboard Time Period and "Yes" for the Rolling Start Time. So that seems to be right. Is there an issue with the calculation?
