When I set the Loan Status to Loaned Out, I get DVDs listed that are not loaned out (they have been, but they were returned). The Loan Status icon is not highlighted and hovering over it shows that the DVD was loaned and returned. The particular one I'm looking at was returned on 4/29/07, so that would've been when I was running an earlier version of DVD Profiler (I'm running 3.0.3 right now). Could that have something to do with it?

Interesting. I just tried marking it loaned, and it removed it from the list. Clearing the filters and checking on it shows it still marked as not-loaned. Turning on the filter again and it no longer shows up in the list.
