 Initially when he posted before the pics i thought because it was expecting a debit, but an IC doesn't normally trade for a debit, it was getting confused and crediting the difference. But he clearly selects credit in the pics so now idk. 
  
 All sorts of crazy shit is possible with this platform. Look what you started 😂
