Missing Primary Point of Contact and Assigned To when Ticket Has been assigned

Summary: The "Primary Point of Contact" and "Assigned To" fields are showing as blank on the main agent UI after a ticket has been assigned or moved into a different status other than "New".

Content (required): Primary Point of Contact and Assigned to fields showing as blank on the main admin UI. The fields are populated correctly once entered into the request, but remain blank on the main UI page. Screenshots show that the Request status has been updated and action has been made on these requests, but continue to show blank fields. This seems to be random, no patterns have been identified as to why the fields are becoming blank. We have run "Synchronize Person Records" with no improvement to this.
