Creating own Admin Column with custom plugin

Hey Guys, first of all – great plugin!
I purchased the pro version and would like to add customized fields from Buddypress. The Custom Post Guid from your tutorial is working and i managed to show that in the admin users view.

However, I am not able to get my buddypress fields.

May you give me a hint?
Regards
Mathias
