Could you export, zip up and send us the NL2 Zoom hands via our support system? Given the ratios I suspect it's likely one issue and the 3 hands that don't convert will likely tell us everything we need to know.
You don't have to send us your hands of course, but if you attach them to a ticket they are private and will be treated in complete confidence. Only our support staff will see them and they will only be used to investigate your specific issue.
