Why The invoice showed paid even after I deleted the payment entry.

May Lee

I found a weird situation. My invoice showed a double entry of the payment with the same transaction number and then showed it is a negative balance. After I deleted the payment entry, it still showed it was paid, though the invoice balance is not zero. And when I do the customer statement, it shows it is unpaid. And there is no button to click make a payment as the status is paid. What can I do to fix this? I have attached the invoice and statement for your information.

Many thanks.
