I took a "duffel bag" and put it on my back and they didn't show up on the right side icons indicating the bins. then I realized that the icon of the bag is completely black and that is why it could not be seen but by placing the mouse over it you can see

In the same store I found a "Paper Bag" with a "?" as an icon, even when the item was left on the ground, this same icon would appear.
