Several possible reasons.

First possibility:
The connect you provided to RMAN was local and not for a catalog.

If the backups are done through a recovery catalog then they are managed from the catalog and not from the control files.

Second:
The archived redo logs you see on disk aren't part of the managed files from RMAN.

Third:
It may be possible they are still necessary for recovery and cannot be deleted.

Fourth:
Possibly a few other ways.

If you can, please post your RMAN backup scripts.
