The option "Create New UI Config" is not visible in BCUI.
Employee Central: BCUI
The "Create New UI Config" is shown if "Enable Dependents management" is enabled in Provisioning. Enable Dependents management from Provisioning. Also run the job "Synchronise Business Configuration" in Provisioning. This should resolve the issue in BCUI.
