Something strange is going on, When I enter a new customer, the Billing address is refusing to allow me to put the Street, town and city onto different lines (as you would when sending a letter). When I imported the names and addresses, I was able to go back and hit the return key and put them onto separate lines. But when I go to add a new address, it refuses to allow me to put the address onto separate lines, and has to come out all on one line.
But if I put the same address into the Delivery address, I can put them onto separate lines.
