LUNs Private after Deleting DVOLs

I created a file storage pool from a mixed block pool by creating 10 luns and assigning those to the ~filestorage storage group.  I decided to destroy it and recreate a smaller one. So I deleted the VDMs, cifs servers, and file systems and then went to Storage->Storage Configuration->volumes and deleted the now unused volumes.  The file storage pool went away as expected; however, the LUNs did not unbind but instead were moved into the private luns folder.  This of course is any issue since I cannot delete them and they're still using space in the my mixed pool.  How can I get rid of these luns?  If I right-click and delete them, it says success but they do not get deleted.  I've rebooted the SPs and the data movers but nothing helps.  I had created a snapshot, but deleted it and there are none now.
