Hi Team,
I am encountering an issue with managing customers in Jira Service Management. Specifically, I have a user who has used three different email addresses over time. Despite deleting this user under Project -> People, the customer still appears.
Notably, when I check under Admin -> Users, this user is listed only once. Could you please advise on how I can remove this customer permanently?
Admin-User Console:

Project-People - this user is not available:

Project-Customer

Thank you for your assistance.
Best regards,
Christian
