XF 1.3 custom field not showing on registration page

I am trying to have a field on the registration page with tick boxes or radio buttons, e.g. How did you find out about us: Friend/Website Link/ Web serach/other

In Users> Custom fields> Create I ticked Show during registration but it does not show on the registration page.

I thought this is how it would work, am I missing something obvious?
