When you edit the customer address / product details during create an order, if you delete a line of text, it shows correctly on screen. However, the printed label (and entry in the address book) has the original line of text rather than the blank field.

The only way around this is to edit the address / product data in the address book / product list before creating a new order.

This needs correcting, as I often end up having to request a refund for labels because of this.
