How to change names in helpdesk

Hi,

We are facing an issue where all names displaying in helpdesk (contacts, assigned to, and team members) are pulling in the user's full legal name. We would like to change this to just first and last name. Changing the format in Core HR does not work and I read another post on Customer Connect asking the same question but there was no answer provided (https://community.oracle.com/customerconnect/discussion/763320/can-we-make-changes-to-name-format-in-redwood-helpdesk?utm_source=community-search&utm_medium=organic-search&utm_term=How+to+change+names+in+helpdesk+)

Has anyone faced the same issue and been able to solve it?

Thank you for your help!
