Zoom Phone - Display Name Problem

[TomV]

I am a Zoom Phone Business Admin.  I recently set up three new users over the last week.  Two of the users are fine and set up did not look odd in any way.  One of the users has a problem: their display name in the Zoom Phone system is displaying as their email address rather than first and last name.  

Does anyone know of a way to force the phone system to use their first and last name rather than email?  It is effecting things like outbound caller ID and searches for the user.  The only way I was able to fix this in the past was by removing the user and then adding them again, but this user is already using their account daily so I do not want to cause a loss of service if I can help it.

Look under "User Management" (not "Phone System Management") and make sure their Display Name is correct in their profile.
