Recruiter receives additional notification with the interviewer name when an interview is scheduled

Hello,
We are observing unexpected notification behaviour while scheduling an interview.

When creating and scheduling an interview:

1. As part of the Interview Scheduled notification to requisition owners, both the Hiring Manager and Recruiter correctly receive in-app and email notifications.
2. The Interviewer also correctly receives an in-app and email notification under the Interview Scheduled to Interviewer alert.

However, in addition to these three expected notifications, an extra notification is being sent to the Recruiter, which specifically includes the interviewer name.

Could you please clarify:

• Why is this additional notification being triggered for the Recruiter?
• Is this intended standard behavior or a configuration issue?
