Full Name Not Updating After Changing Preferred Name + Last Name Format

Summary:

Content (please ensure you mask any confidential information):

Hello Experts,

I recently updated the Full Name format to use Preferred Name + Last Name. However, when I check the Personal Details page for existing workers, the Full Name is not updating to reflect the new format.

I would like to check with the community:

• Is this expected behaviour when updating the Full Name format?
• Are there any background processes, HDL methods, or profile options that can trigger a recalculation?
• Has anyone seen this issue after modifying the name format?

Any guidance or experience from others who have updated Full Name configurations would be greatly appreciated.
