Hi,
Your screenshots does not seem to correctly display the issue.
If your Credit Memos are already fully reconciled in Version 2007 with Invoice or any other relevant transaction, then the same should not appear in the Incoming Payment window.
If they are not reconciled or are partially reconciled, then they can appear in the Incoming payment.
You can check the details of the reconciliation related to the Credit Memo by opening the Credit Memo and right click > Reconciled Transactions and check with which documents are reconciled.
Kind Regards,
