I am using Ultimate facebook for adding FB connect

Hi,

I am using Ultimate facebook for adding FB connect and Mailchimp plugin to sync with my mailing list. However, the sync with mailchimp has stopped working recently. The log says the below
[May 23, 2013 9:39 am] [CODE:250] [EMAIL:xyx@hotmail.com] - FNAME must be provided - Please enter a value

What mapping should I use in the Ultimate Facebook plugin to fix this problem?
I have the following mappings already in the Facebook Connect tab -
first_name -> Name
last_name -> Last Name
description -> Bio
date of birth -> Birthday
city -> Location
username -> email
nickname -> Name
first_name -> First name

Also, it would be great if a delete option is given for the mappings. And, add a header to indicate which column is for Wordpress fields and which one for Facebook fields.
