Address on Separate line

Under contact address, I've noticed that everything appears on one single line.
Eg. if I key in on the back end ... address:
Apt 215, Backrow avenue
456153, Street 12354
USA 2345
All of it appears as Apt 215, Backrow avenue 456153, Street 12354 USA 2345

Can I do anything about this?
Need to fix this, as some contacts have 2 addresses, so can't have them all on one line.

Thanks.
