Amount of Items Received from Encounters


I have been battling, to learn spells, and have noticed that there is an inconsistency between how much of an item it says I get from a battle and how much actually goes into my inventory. For example, it said I got "Smoke Bomb x2", but my count in my inventory only went up one more from what it was. I'm not sure how else this might effect items from battles, but I have at least noticed this much.
