Lot Quantity reserved for order

I am using sage 300 IC 6.0a PU 2 ,

I have one item which shows lot  qty reserved in an order, I have looked into OE Backorder for the item , but I couldn't find any.

I need to clear this  lot qty reserved as it show available in Lot reports but physically not,  and cannot reconcile  ( ship) it as it does not appear in the IC reconciliation.

Please advise\
