XF 1.3 Users can't register. Template issue?

[oVR]

For some reason new members cant sign up. I believe it to be a template issue that has duplicate entries and thus confusing users.

This is what it shows: http://gyazo.com/a5a585e3b869d86de44ce3f3ffd29929

Solution?

That would be a modified template (the register_form template) or a third party addon.
