RMAN - Not reporting backups

I am running RMAN on a 9i database with the following parameters: CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS; and
control_file_record_keep_time = 21  

I have run several days of successful backups. But when I do a list backup, I only get the last backup listed.  

I am not using an RMAN catalog.  

What am I missing?  

Thanks!
Ron
