Avatar and Cover fields not appearing when registering with Facebook

Hello

I use ES with JFBConnect integration. When a user tries to register with Facebook (JFBConnect), at the step "Appearance" where the Avatar and Cover fields are supposed to be displayed, these fields are not showing...

Please see the attached snapshots, registering with JFBConnect and registering normally without Facebook (which works fine).

Note that if the user skips the "Appearance" step, avatar and cover are retrieved from Facebook to create ES user profile, as expected.

Thanks
