To fix this issue:
In View Sales Invoice, click preview, click settings, and customize the report template (EINVOICE_INV.FRX).
In Report Designer, double click on the QR Code picture, changing the QR Code variable to "get_qrimage(artran.type,artran.refno,artran.date)" as below the picture, and save the report template.
Go to regenerate the PDF file for the invoice reference (example: 00175265 and 00175266).
Scan the QR for both invoices and display the information correctly.
