RTV Replacement - Voucher matching to wrong receipt

I have a question about the matching process for a Re-Bill - or RTV Replacement.

1: PO line is originally received in and RECEIPT A is created

2: PO Line is Vouchered, matched, approved and posted

3: PO Line is RTV'd for Replacement - RTV Created - PO Line reopened for receiving

4: Credit Memo is created

5: Voucher is matched against RECEIPT A with a credit

6: PO Line is received in and RECEIPT B is created.

7: Voucher is created for PO Line

8: Matching Process Runs and for some reason Matches against RECEIPT A (I am expecting to see Receipt B)

I am looking on the Regular Entry screen - Related Documents Tab under Voucher Line - Receiving Information (See attached Picture)
