Payment Duplicate Issue on Bank Transaction

Hi dev13 

Thank you for the detailed screenshot.

Bank transactions can be matched to open invoices, which would create the payment transaction automatically to close off the invoice. In your case, the bank transaction was matched to the remaining balance of invoice 14222, which creates the payment activity of CR000390 thus closed the invoice. 

Since the payment was already recorded via API (CR000389), the bank transaction should be matched to this payment instead of the invoice. Please undo the matching then match the bank transaction to CR000389 so there's no double up.
