Duplicating Social Login fields

​Hi
For my site Politics.scot, I am using the ‘Bimber’ theme, which recommends using plugins ‘Snax’ and ‘WordPress Social Login’, see:
http://docs.bimber.bringthepixel.com/articles/community/login-popup/index.html
I have followed the instructions to set up Social Login / Snax, and for some reason the login buttons / fields are duplicated, on both the popup (when you select submit new link) and the Buddypress reg forms, see:
https://politics.scot/register/
You’ll see on the reg forms the text “Or register with your email”, “Register with your social network:” is duplicated. On the popup it duplicates the buttons.
I’m guessing I’ve twice enabled an option somewhere between the two plugins but can’t find where.
I have enabled Support Access.
Thanks, Neil.
