Assigned To Field Users are Empty, but when I lookup users from list view they appear

[JbDevelopsSnow]

Trying to figure out how to resolve for an issue, I have the assignment group populating only at the list view but not when in the record.   No users appear when I look them up in the assigned to field while in the record but in the list view users appear when looking them up.  Any ideas why?

It may be a dictionary override. I believe only users with itil can see incidents OOB

I am trying to get the assigned to to populate, its not even populating for admins
