Example of the problem... I have 4 of one type of garland in my ornament inventory. I want to remove 3 of that garland. After all, why would I need more than one of each in there? I select the drop down menu and click 3. I then click Remove Selected Items to Inventory and find that all of that garland have been moved, not just the 3 I selected.

This happens with all of the ornaments that I've tried so far. Right now I find that I have to remove all of that ornament and then individually add one back into my ornament inventory.
