Build Sheet QUESTIONS

From my research if the build sheet came from the back seat - first digit is a 3- after January 1970 all showed this flaw and had no codes after line 7.
Sheets that came from front seat or floor, codes 1 or 2 would have a full correct build sheet.
It was the printer off the seat line 3 that had this common error

Would like more info please including dash VIN to further help.
