RDX 1000 fldr moved to different media set - need to move back to "Backup Exec and Windows NT Media"?

I was moving some things around deleting old jobs,catalogs, media sets and at some point was prompted relocate the media because they had to be moved.before whatever object I was trying to delete could be deleted.

The folders fldr00000011, 12, 13 and 14 are stuck in custom set, "RDX1000 Media Set 1".
 

This thread says RDX1000 fldr00000 folders cannot be moved and are placed in "Backup Exec and Windows NT Media"  http://www.symantec.com/connect/pt-br/forums/backup-exec-2012-rdx-cannot-move-scratch

How can I move them to "Backup Exec Windows and NT Media" where they are supposed to be, by default?
