Unable to match invoice to PO after canceling incorrectly matched lines.

Hi,

I am unable to match invoice lines to a PO after having to cancel some lines on the invoice that were matched to the wrong lines on the PO.

These invoices were uploaded through EDI, and I could not reverse the lines or correct matched invoices before resorting to canceling the lines.

I am now trying to re-match, but the PO does not appear after performing the search that pops up after clicking on the button next to the Match Invoice Lines option.

Also, I have tried manually creating the line and typing in the PO number at the line level, but it still fails to find the PO.  Both the lines and the PO are in the "Open" status.
