User Modification Template Issue

User Modification Template Issue

I just upgraded to the new 6000 build and I'm seeing a flaw in the user modification template. I'm utilizing the default template layout. I am unable to set my mail server and mailbox store because those fields are greyed out in the template. Unclear why those fields are blocked since I'm using the default layout.
 
I'm currently awaiting a call back from Technical support as they try to figure this one out.
