Are you using Electrum's ZBar scanner (Tools->Load transaction->From QR code) or a third-party QR code scanner?
Because AFAIK, the latter will produce problems with the scanned transaction.
Yes, using the Electrum Scanner, but I even used non-Electrum scanners on both ends to construct the transaction to QR and deconstruct the transaction to text on the offline machine and then import as text. Both attempts had the same issue.
