Please run TMSUPDTE and REP FLAG2=01 and EXPDT=today's date or a date in the past which is what you have done. The next run of TMSCLEAN will scratch the tapes or you can use the CA 1 ISPF utilities and request the tape to be scratched.
FLAG3=20 which means it is controlled by an EDM. Change FLAG3=00 and then rerun TMSCLEAN and it should now go scratch.
If that doesn't work, please do the following and it should go scratch.
REP FLAG3=HEXZEROS (FLAG3 can't be marked for EDM or the tape won't go scratch)
