Hey, I've created an invoice and I've filled in the "ship-by" field by error, but now, each time Icreate a new invoice, the "ship-by" field is pre-filled with the value I've put in the first time + it is printed out on the invoice when I forget to delete it manuallt. Is there a possibility to not show the "ship-by" field on the invoice (or to delete that first value)? I've tried putting in a "space" but then it shows "Ship by: " on the invoice, and that's not ideal... Thanks Michel
