PO Receipt is Missing? E-Business Suite 11.5.10

I am having an issue trying to receive two lines from a purchase order in E-Business Suite 11.5.10

The system generated a receipt number for us, but when we go to receive the lines, it is saying the receipt number is invalid. Same thing when we try to enter the PO number.  When I go into the receipts window and enter in the PO number again, the system shows that there are no items left on the PO to create a receipt for. The lines are stuck somewhere between receipt and receiving.

The PO lines are approved and in open status. The parts on the PO are mastered correctly. I have checked the pending transactions and the receiving transactions, but there is nothing in either.  I have checked the PORCPT workflow, and nothing is in error. The receipt is stuck somewhere, but I am not sure what else to do?
