FOB Destination PO Receipt is created for the delivered performance and not Received/Accepted

We are implementing G-Invoicing on 12.2.10. For FOB destination, interfaced the delivered performance from G-invoicing to EBS. The receipt data in PO_IGT_PERF_TRANS_HISTORY table has Pending Receiving status and the PO Receipt is getting interfaced with the delivered performance instead of the Received/Accepted Reference Performance. Reference performance pushed to G-Invoicing is displayed as Receipt with the received/accepted, the settled performance from G-inv is interfaced as AP invoice. But the PO receipt is having a different quantity than the Settled quantity.

Is this a gap?

For example:- Data resulting the discrepency is as follows:

IGT Order - 64
