Not seeing Cleaning Tape in assigned slot

We have a DELL tape library with two drive. The Cleaning Tape was assigned to slot 23 from the DELL management utility. When I go onto Backup Exec 2012 SP4 I am only seeing 22 slots. 1 is assigned the I/O slot and 23 Cleaning. I did an inventory, scan etc but still not able to see the cleaning slot. I would like to apply it to the Cleaning Media Set.

Any assistance is welcomed.

Thank You
