Mapping Profile Fields using Cimy & Ultimate Facebook

I am attempting to Map WordPress profile to Facebook (see attached). I have used a plugin called Cimy to define some additional profile fields (see attached). None of the custom fields are being populated with profile information.

When I register via Facebook, a new user is created in the Wordpress database, along with name, bio and profile picture - so all is working as far as the default configuration, but nothing happens in the custom fields.

Is there a preferred method of adding custom profile fields that I should employ, rather than using Cimy?

Thanks for any help you can offer.
