Scanning QR Codes

[MauriceWhelan]

Hi. I have 2 copies of the same QR Code that I need to scan. When I scan the black QR code it works instantaneously and returns the correct value every time but when I scan the white one it can’t seem to scan it and one the odd occasion it does scan it populates the field with a bunch of numbers. I downloaded an external QR Code scanner which scans both and returns the correct value for both everytime without issue.

Is there anything you could maybe advise on as a possible issue?
