Why does the original recruiter’s information remain when I change "Primary Contact"?

Problem: I'm trying to add a new contact for a visit by clicking 'Revise Primary Contact' and entering the new information when editing the interview, but it still shows the original recruiters information. How do I add a new recruiter for this visit.

Resolution: The 'Revise Primary Contact' utility was designed with the intention to update the recruiters information OR to change the primary contact for the visit. If you want to select a recruiter that is not listed in the drop down list, you need to create the recruiter's account under the proper organization first, then that recruiter will be available in the drop down list.
