Dropdown selections from app to app relationship

Jeanette, I read this a couple of times and I don't quite understand the issue.   Can you help me understand and reconcile these two statements? 

I used this report (of active employees) to pull the selections on the Details table....which is working perfect.

The problem is on the Job parent table where it displays the information from the Details table...it is showing all employees in the dropdown, not just the ones on the active employee report.
