Specific barcode is not recognized

Hi,

I face a problem that I could not scan a specific Code 39 barcode with Vision framework. We have multiple barcode in a label and almost all Code 39 can be scanned, but not for specific one.

One more information, regardless the one that is not recognized with Vision can be read by a general barcode scanner.

Have anyone faced similar situation? Is there unique condition to make it hard to scan the barcode when using Vision?(size, intensity, etc)

Regards,
