Billing Address Displaying Incorrectly

Hi Have just set up a delivery note but the delivery note is not displaying correctly. Its almost like Address Line 2 is missing and one line of text is displaying over the other?
Please see 2 examples:

https://www.diamondaffair.com/wp-admin/admin-ajax.php?action=rednao_wcpdfinv_generate_pdf&orderid=6283&_wpnonce=7d8c8d6283

I do not have the full version and I cannot see how to fix the problem?
