03 Cummins Showing 2 Differnt Vin Numbers

This is a new one for me. When trying to read a 03 Cummins the vin displayed starts with a 1 which is the truck's actual vin. After the supplied generated file is opened, in the calibration details tab it shows the vin starting with a 3 the rest of the vin is correct. When you look at the Tune Overview Tab it shows starting with a 1. I'm unable to flash the file back in the ecm do to the fact HP license the Vin instead of controller serial number. Once again HP you should change your vin policy. The next thing I will try is pulling the ecm and flashing it on the bench to see what gives. Does HP look at any other modules to determine VIN??

Thanks
