Black market issues

After posting an order for 1000 loose notes, I went back to claim what is left from my order 62 worth of loose notes (62x55=3.410) but the black market only gives you back the value for one loose note $55. It happened to me multiple times with really small amounts of money and wasn't really paying attention what was happening before. But if you want to deal with black market the money you get back from items not being sold should be sorted properly.
