Max Ship Amount hold for Pricing discrepancies

Hi,

My Invoice has two lines both matched to different receipts of a PO.

My first invoice line has quantity 0 and invoice unit price .025896 USD whereas the associated PO line is of quantity 5000 and PO unit price 0.25. The invoice line has ordered qty 5000, Received Qty 5000 and Billed Quantity 5000. Max ship amount tolerance setup for Goods is 10 USD.

So ideally, according to formula (quantity_billed * invoice unit price) - (quantity_ordered * PO unit price) > Max Ship Amount Tolerance, (0*0.025896)-(5000*0.25) = -1250 which is < 10 USD.

So though my quantity (ordered vs billed) matches, the price does not match. The invoice should not go on hold according to formula but invoice still imposes Max Ship Amount Hold. Why did I get this hold and how can this hold be cleared?
