Capacity Manager displays tablespace status that was dropped for a long time (4240610)

A tablespace was dropped a long time ago but Capacity Manager is still showing it in the console tree. According to help file, under topic "A look at the Capacity Manager Tree", indicates that a tablespace may be shown as historic and it is shown when a tablespace is found only in the repository but not in the data dictionary for the monitored database. This circumstance can occur when a snapshot has not been collected since a tablespace was dropped. The tablespace node is cleared the next time a snapshot is collected for its database.

However, the snapshot job has been run successfully many times.
