Misaligned text box in drag and drop interaction

It looks like whatever state you're using for dropped items is different than the items Normal state. For example, notice the strange borders for the Ped and Coban items. And the text for the IV Kit has a different alignment. 

If the dropped state has different dimensions than the Normal state, that might be causing the problem. 

I suggest you do this: 

• Verify that each draggable item (and all of its states) are the same size. 
• Make all the targets that size (or just slightly bigger). 

If that doesn't solve the issue, upload a copy of the Storyline file, because that'll make it easier for someone to troubleshoot.
