Duplicate values appearing for Person Type “Nonworker” in dropdown

Hi everyone,

We are facing an issue with the system person type “Nonworker.” In the user person type dropdown, the same value is appearing multiple times, even though it has been configured only once in the setup.

Has anyone encountered this issue before?
Is this a known behavior, or is there any fix or troubleshooting step we should follow to resolve it?

Any guidance would be appreciated. Thanks in advance.
