wrong volume type in NSM 3494

Hello,

I filled the Convenience I/O Station of a IBM 3494 Tape Library with 30
K-labeled (3590 extended length Cartridges). They are numbered from
050000 to 050029 by Bar Code label. 29 Cartridges get the rigth Volume
Type,
one Cartrigde (050016) get a wrong type and cannot be checked in:

%mtlib -l /dev/lmcp0 -qV -V 050016
Volume Data:
   volume state.........00
   logical volume.......No
   volume class.........3480 1/2 inch cartridge tape
   volume type..........CST-2 320m nominal length
   volser...............050016
   category.............FF00
   subsystem affinity...01 02 03 04 00 00 00 00
                        00 00 00 00 00 00 00 00
                        00 00 00 00 00 00 00 00
                        00 00 00 00 00 00 00 00

The other cartrigdes shows (for example 050017 after checkin):

%mtlib -l /dev/lmcp0 -qV -V 050017
Volume Data:
   volume state.........00
   logical volume.......No
   volume class.........3590 1/2 inch cartridge tape
   volume type..........EHPCT extended length
   volser...............050017
   category.............012C
   subsystem affinity...01 02 03 04 00 00 00 00
                        00 00 00 00 00 00 00 00
                        00 00 00 00 00 00 00 00
                        00 00 00 00 00 00 00 00

After ejection of cartridge 050016 with the command:

  mtlib -l /dev/lmcp0 -C -V 050016 -t FF11

there is no Information about this cartridge in the Tape Library.

I take another K-labelled 3590 cartridge and placed the Bar Code Number
from the 050016 cartridge on it and inserted it in the 3494. The effect
was the same:

   volume class.........3480 1/2 inch cartridge tape
   volume type..........CST-2 320m nominal length
   volser...............050016

?????



Thanks in advance,
