[Plugin: WooCommerce – Excelling Ecommerce] Have First/Last Name Upon Register

Hi, i’ve been trying to include first and last name in the registration process on my website, however, i’m not sure how to have these details actually register. For example, i’ve got the fields showing, but even if you fill in the fields, once the account is created the fields do not populate in billing details or anywhere and i’m unsure how to do this. My website is http://lavishthieves.com.au for reference.

Thanks in advance!
