BuddyPress.org

I am running WP 3.5.2 and Buddypress 1.8
My domain is http://www.calvarygo.com
and is a fresh install with the custom community theme.
here is my problem.. i successfully edited the Nickname Profile field to ‘First name’ via Admin>User>Profile Fields
it worked for a few days but now has reverted back to ‘Nickname’ when you view it in admin or the Registration Page.
Strange thing is when i go to edit it, it shows ‘First name’ then i save and it shows ‘Nickname’ and of course it shows ‘Nickname’ on the reg page..

I beleive this is plugin related and have narrowed it to ‘BuddyPress user account type lite’
and ‘User Role Editor’ This happened to me a few days ago and i just deleted everything and reinstalled WP and BP.. how ever i really dont want to do that again!
Please assist as we are looking to go live in a week…

Thanks!
