I permanently get notifications about Jira issues I am not watching. That happens with issues of all projects I created - although
- I handed over the project lead
- I am no more listed in the "people" section
- I already did a bulk rework "unwatch all issues" for that project.
See this example notification mail:

and the return of the notification helper on this issue

As far as I understand the notification helper is right: I should not receive notifications for this event.
The problem is: I did. I always do.
Can you please help me understand the settings and getting rid of issue notifications I don't want to receive?
Thank you very much and best regards,
Jakob
