If this continues to happen to your inventory, try de-cluttering it. It happens to me when I'm carrying too many items; as soon as I drop some stuff off or put them into sacks, the problem goes away and I can clean up the mess the bug made in my inventory.

I have my containers at the top (arranged by image shape/style), followed by my armor (arranged and grouped by type and placement ie. cloak above armor), amulets (arranged by image style), followed by weapons (grouped by image style), tools (arranged by image style), rods/wands (grouped by spell and weight), maps, rings, and the rest is random stuff I may happen to pick up or get through trade.

Yes, I'm anal.
And proud.
