i have occurred something strange

there are some supplier invoices in system that have been matched with Po receipt and posting information has been created based on Matched Po Receipts (Transaction Code is not manual).

So if I query Matched Receipts in Supplier invoice i will see Receipts that have been Matched.

 but I don't know why in some cases when I click on query Matched Receipts , I don't see anything in “Query-Match Receipts” Window whereas i expect to see Matched Receipts, because  user has Matched the Receipt in supplier Invoice and if I Create new Supplier Invoice I can Match Again new Invoice With The same Receipt
