When users send a mail to the company's Physical voucher (inbox) Uniconta scans the text in the mail for words that it recognizes and enters them in the fields (e.g. amount, invoice number, vendor, bank, IBAN etc).
If something is entered in the Payment ID field that does not make sense then it has been picked up in the email in error and should be removed from the email.
If the problem persists, please try to delete the layout.
