Scoped Application - Workspace

[Wardma]

Hello Fellow Devs!
Im working on a scoped application and Im trying to utilize the contact card feature to display relative information and I've gotten as far as pulling the information from the look up record/user items. When attempting to reference the return fields for the headings within the contact card it pulls no data. Im sure I could be doing something wrong and as the documentation suggests I dont really see what the issue is. Any guidance would be greatly appreciated. 
General idea of what I am trying to do; 
Referencing the sys_user(caller_id) field on a incident that is the reference to the sys_user table. Using this I look up the record of the person in the field, return only fields I want from the user profile (ie; name, title, email, location.city, location.country). 
Im trying to keep these fields dynamic based on the caller field.

I was able to make the name on the contact card dynamic, but replicating this to the other fields didn't work.
