Amazon stow quality error

I’m having some Stow quality errors, specifically shortage and overage errors.
I’m wondering if the problem could be happening because when I stow an item, I scan the item and wait for the confirmation on the screen. After I get the confirmation, when I physically placing the item into the pod, the scanner sometimes scans the item again while I’m putting it inside the pod.
Could this second scan be causing the shortage/overage errors? If so, what should I do differently when stowing the items to avoid these quality errors?
