RMAN 8i - V$BACKUP_SET still holds records after they have been deleted

Question

Hello,
I am using Oracle 8i version 8.1.7.0 on Windows 2000. TSM (Tivoli) is our storage manager. I am attempting to clean up backups that I consider obsolete. I am NOT using a catalog for the repository. My criteria is:
1) List the backups to delete using -
report obsolete redundancy 2 until time 'SYSDATE-7' device type 'sbt_tape';
2) I use the RECIDs listed on the report and issue -
CHANGE BACKUPSET nn DELETE;
RMAN acknowledged the delete worked and the report command used in step 1 no longer lists the backups. Good so far. In order to cleanup backup_sets fo archivelogs I list the "obsolete" logs using the following SQL:
select recid, backup_type, completion_time
from v$backup_set a
where backup_type = 'L' and a.completion_time < (select min(b.completion_time)
                    from v$backup_set b
                         where backup_type = 'D');
My logic here is that any backup_set of logs completed before the oldest database backup is no longer needed. The problem is that even though the "report obsolete" doesn't list them, they still appear in the V$BACKUP_SET view. This foils my method for determining the backup sets of archivelogs that I can delete. Why would the deleted database backup sets still appear in V$BACKUP_SET? Please remember I am using only the controlfile and NOT a catalog for the repository. Does anyone have any ideas?
Thanks,
Richard
