STAAD Planwin License on Hosted Select Server

I would like to ask how the STAAD Planwin license was used or activated on user machine. We received two email notification from SELECTserverOnline@bentley.com stating two users have utilized the license. I'm trying to restrict it from our hosted select server - checkout restriction but cannot find this license file from the list. See embedded images. How come there is an overage use of this license when it is not appearing on the list?
