Two questions, one principle. The master bill and the CF214 line are not counting the same thing: the bill records physical cartons once, and each line records its own transaction quantity, so zeroing packages on lines two onward is very likely intended, not an error. That holds at six pallets and thirty-plus HTS numbers too, machines and components alike, because the count that changes is transaction quantity, not carton count. Confirm the exact field behaviour with whoever built your entry software, because that detail is implementation, not regulation.
