When adding new tasks for blank media in DiskXtender Administrator I receive the following error when adding a new Move Group.

"Warning - there are no move groups belonging to this media's extended drive that can accept this media. This media cannot be added to a move group at this time." (See screenshot at the end of this post). I am adding new media the same way I always have. Any thoughts?

Version info:

DiskXtender Administrator v5.20.150

MediaStor Administrator v5.20.150
