I had a problem with this and searched the adsm.org and found
a tip (don't recall from whom - but thanks) to use wildcard
delete rather than name etc.

I did this:

 adsm> delete backupset * * begind=03/01/2001 endd=-14
 ANR2365I Backupset MACOS9.412.336789572 for node MACOS9.412 has been deleted.

 adsm> q volh type=backupset
 ANR2034E QUERY VOLHISTORY: No match found using this criteria.
 ANS8001I Return code 11.

and it worked for me ... it may work for you (let's hope so).
