report obsolete and list backupset don't match

The problem I'm having is there are RMAN backup files on disk that aren't listed when a "list backup summary" command is run, but they are listed when a "report obsolete" command is run. 

Notice the following two commands, the 1396, 1397, 1398, 1399 backup sets are missing from the list backup command.  The actual backup files do exist on the file system and if I add them to the control file the list backup command will show them.  Before we run a delete command after the backup we check for files that aren't backed up three times, since the oldest backups aren't in the control file, the redundancy check fails and the delete script doesn't run.
