Error with existing WP account trying to take course

Steps to duplicate:
1. Existing WordPress account, does not have first last name associated (this is typical)
2. Install Lifter
3. Add demo, or any course
4. Existing user tries to order free course, give an error about first name and last name missing and is now stuck

I see the obvious issue, I want to require a first and last name. The existing accounts don’t have this. There should be a better flow for the user, such as taking them to the checkout to add this info, versus just saying its required on the course index page, but there is no place to add it there.
