Networker VTL Reports Tape Unlabeled

Good Day Experts,

We are using Networker 7.5.1 on a Windows 2003 R2 SP2 server.  We have two storage units attached to this server, one is a EMC CDL310 and then other is a Dell Powervault 132T.  The problem is with the CDL310 unit.

Every once in a while a tape in the CDL will report as <unlabeled>.  Doing a search through the media save sets, the server reports back that there are save sets associated with the volume.  For the attached image, this tape reported fine yesterday and was used last night for backup purposes.

I attempt to do an inventory on the tape and it still reports as unlabeled.  Mounting the tape fails with an error 'error message: Expected volume `-' in slot `36'. The actual volume is `<NULL>'., Expected volume `-' in slot `36'. The actual volume is `<NULL>'.;

Just curious if there is a way to 'recover' the tape into a usable mode.  I am aware that if I re-label it I can use it again just fine.  However, its frustrating because once I re-label the tape I know longer can recover data off this volume. Networker VTL Screenshot

Discussions with support had me ensure that the option was enabled in the library configuration to 'Verify Label on Unload'.  This is suppose to have the library check the tape label before placing it back into it's slot.  So far so good with this option.
