From another thread, the deletion is a separate task from the group:

Delete records older than (Transaction Groups) - How does this work?

A vendor once told me this: Es. for “Delete Records older than” X : X < 1 hour, the delete task execute every minute 1 hour< X <12 hours, every 15 minutes X > 12 hours, every hour Of course in addition to @PGriffith’s answer

That said, is there anything in the log?
