Candidate duplicate check notifications are NOT triggered even when duplicates are found

Summary:

The duplicate check match score in CSP is set to "low" and delivered duplicate check notification is select at various states in the CSP. Even though the duplicates are identified when checking manually, no notifications get triggered to the recruiters. Infact, I have NEVER seen this notification work. Has anyone else experirenced the same? When does this notification actually trigger?
