OK, so I've gone through my drives, mounting and unmounting from within Bacula and then checking those results in MTX to see if there are any discrepancies.
I should note that I modified my SD config file to change the device names to match the drive index. Maybe I should have waited to make that change until after these tests...... wanted to mention it in case you notice a change in drive numbers.

If this is not a blank tape, try unmounting and remounting the Volume.
MTX shows the correct volume label:

Any ideas why this would happen? This also explains (I think) why the jobs were asking me to mount a volume or label a new one.......
Thanks,
