Partially paid PO line(type goods) is not avaiable for matching

Summary:

We have a PO created with a line type goods as below.

It is matched to an invoice and paid fully as below

We have matched 600$ to this invoice and now wanted to pay the remaining $660. But the line is not available to match.

What went wrong here? We have upgraded to 25C recently.
Any solution?

Please advise.

Thanks
