Here is my more detailed description..
Looting Stackable Items
- Be in possession of stacked items (let's say a stack of 15 bone chips)
- Kill something which drops bone chips
- Loot the mob and grab the bone chips by RIGHT Clicking (which places the item into inventory, adding to the existing stack)
- Examine inventory.. Bone chip stack will not show 16 bone chips.. it will show 1
<Note> I believe this happens when stacked items are in a bag and also when in a primary inventory slot.
- The only way to avoid this is to LEFT click to loot and place it into the existing stack in your inventory.

Selling Stacked Items
- Be in possession of a stack of items (let's say a stack of 15 bone chips)
- Visit a vendor (I did this with Sneed Galliway in North Qeynos)
- Click on the stack of bone chips to sell
- Click on the sell button
- Inventory shows a single item of the stack is left in inventory.
- Click it to sell
-Click on the sell button and receive a message from the NPC (something like whoa slow down.. One item at a time! -or- You seem to have misplaced that item)
- Exit the vendor screen and try to right click him to sell again. You can't. In fact, you can no longer click on anything..
<Solution to this state of being stuck.. Jump>
- Only way to remove the ghost item is to destroy it
