There is a bug in NSSPro that causes the HW Version (Hardware Revision) to be read and subsequently set to the first four digits of the product code. Chris at GenieProjects is aware of the issue but doesn't have an N9 at the moment to debug it. If you put the correct code in the HW Version box and enable only that field it does set it back to the correct value although you are probably better of heeding the advice of others on the forum and not changing the code at all.
