Not using all 10 tape drives keeps saying pick from 0-5

I have a IBMTS3310.  I have 10 drives and up to say a week or two ago I have been able to use all 10 drives.

Server is windows 2008 R2 SP1

Master/Media is the same server

Netbackup 7.5.0.6

Here is what I am seeing when I go look at the storage units.

It says ten but when I try to save I get this error.

Windows see all 9 "One is down for repair"

Here is what I see on the activity monitor

IBMTS3310 see all drives working fine

I have deleted and re added these drive.  Installed the updated drivers, up graded the code on the TS3310 nothing has worked

Any suggestions or help would be great I need all these drive or my duplications will take forever.

My setup for backups are

All but Lotus notes for the a IBM VTL, then are writen to tape on the IBM3310.
