Ah, so it used your rankings, but reset your list after the draft? That's probably just a bug... I'd put it in the thread tzent started for bug reports.
As for the 5th rounder-- was that for some sort of positional need that you established? Was it a pick of a totally safe guy because of your aggressiveness settings for 2-5, and then you had different settings for 6-10 and the guy on your list became eligible to be drafted again? Just spitballing here, it could be a bug, too.
