Trying to delete obsolete backups but RMAN want to delete all

Hi

I am using the rman delete obsolete command. We have a retention policy of 7 days but rman is trying to delete all of my backups not just ones that are older than 7 days. Am I doing something wrong? Any ideas?


Thanks
Kim


PS. Not sure how many points to assign to this. I do need an answer by today but I am sure there is simple solution.....
