when i select the customer in delivery note, the address field is not getting populated. I guess this is a small bug with an update.
if you have a different delivery address saved for the customer, this will show on the delivery note.
if the billing and delivery address is same and you have left the delivery address field blank for your customer, then the address will not show on delivery notes.
this was already noted and informed on the forum.
i do not know if there is any plans to fix this. maybe @lubos can answer.
