I empty my pill bottle containing Amoxicillin while I was at the junk market...

What the game did is put it with the "Items on The ground" and I cant no longer retrieve it!!!!
On top of that..... seem that "Items on the Ground" is also the store... so... I didnt even get the money for the game putting the pills with "Items on the ground"

How do I recover them? Is this interaction intended?
