General Support About a register page

I'm using Klein theme to build a site. (you guys have helped me so much so far!) It seems like I have one last issue with the site. Visit http://www.leastinvasivefirst.org and click "register". Now notice on the register page it gives users the option to change their field visibility. I have set that to restrict that option (users>profile fields) to subscribers, but it still shows up on the register page as an option. How can I fix this?
