Agent Performance Report

Hi, I am having a issue of agents not showing up in the ast_agent_performance_detail report. I have tried selecting by group, and by selecting individual users.
Reading on some other posts, I decided to take a look into vicidial_users table. I notice right out the gate, that it is not correct. It is not updated with new users, it still contains old users.
I know for awhile, when adding new users, we were keeping the same users just changing the full name. At least until they told me that is what they were doing and I had them change to deleting that user and adding a new one.
For UserNumber we are using ABA001 What could cause this?
**EDIT**
Now DB is on another server? Would that matter?
