No, you do not need to apply the patch if you see that option. It means you downloaded software package with the patch applied already.
Set "Y" there and you'll disable LUHN check.
UPDATE: I just noticed you say you still get the issue despite of the option being enabled. I advise you to contact our techs for help either using your HelpDesk account at
