Copying invoices from archive will not use updated payment terms, when using ''Use new customer details''

Question

1. Go to an agreement
2. Sales > Create a new invoice and book it
3. Now edit the customer, change some information (I changed Country and address) and change the Payment terms > Save
4. Now go to Archive > Copy an invoice > mark: Use new customer details > Press ok > All information are changed, except the payment terms.

Payment terms should be updated, like the rest of the infomations.
