[Bug] Incomplete/inaccurate search results

I set up a search on my inventory today with the following parameters:

Set owned: Innistrad
Color (one of): Green
Is Foil: False

Then I sorted by name (A to Z)

The results do not show Avacyn's Pilgrim.   I tried modifying the search to "Set Printed In", but got the same result.  As soon as I cleared the filters, I could find it.

Here's the URL from the page with the filters in place: http://deckbox.org/sets/55672?s=n&o … *!c397!795

It seems that the "Is Foil" filter is trumping things.  I don't want to see records (rows) for foil versions, but want to see cards that have non-foil versions in inventory.
