Technician unable to add requester name

Technician unable to add requester name

Good morning! We followed the update chain to get from 10513 to 11100 last night. Now, one of our technicians is unable to add a requester name when entering an incident. He receives a "Requester does not exist" dialog instead of the usual "Requester Name does not exist. Do you wish to add new requester as part of submitting a new request?" prompt. Please help!
