Thank you for the response, @Jan H - WY.
The invoice will not show on the reconciliation page only the payments made. Try to process a receive payment for each invoice. Once done, go back to the reconciliation page and review if you can now see them.
Here’s more information on how to receive payments for an invoice in QuickBooks Desktop: Record an invoice payment.
