[Bug] Qty change makes line disappear from advanced filter results

To help consolidate the multiple lines that ended up in my inventory when 2.0 rolled out, I started working on my Standard common and uncommon cards.  When I made changes to the inventory quantities (placing all quantities on lines with details and eliminating lines without details), the row for the affected card disappears from the Inventory screen when I have the Advanced Filter set.

I was using these filters:

Is Foil = False
Format = Standard
Rarity = Common, Uncommon

Example:

I had two lines for Battle Hymn: 
     one had Qty=7, TradeQty=0, AVR, NM, English;
     the other had Qty=0, TradeQty=5, and no other details.

I consolidated the lines into one: 
     Qty=7, TradeQty=3, AVR, NM, English.  
     I made no change to the third line (a foil copy) that was not 
     displayed in the main screen due to the filter.

As soon as I clicked Apply, all lines for Battle Hymn disappeared.

This happens whether or not the quantities match the numbers present before the consolidation (i.e., combining a "4,0" line with a "0,1" line into a "4,1" line yields the same results as the example above where the numbers went from "7,0" and "0,5" to "7,3").
