Registration page messed up

Hello! I’m trying to integrate S2members and Buddypress custom registration fields. Originally I was only going to use buddypress fields, but there’s one field I’d like to show up in the webmaster’s notification email, so I created an S2member custom registration field (radio buttons: deelnemer(participant) or coach).

Now, I am also using the buddypress version of BAW registration codes and it integrates perfectly on my registration page as you can see here: http://healthadventure.nl/register/
All of the buddypress fields are displayed just fine as well.

However, when I added the S2member custom field, it is now displayed twice. Under the registration code box and to the right of the ‘register’ button. Obviously I only need one. Ideally in the bottom box: profiel details.

Any ideas?
