Summary emails don't seem to work correctly

Hi, I don’t know where to report this. I subscribed for email notifications from the forum, but I selected the summary every two weeks in order to keep my inbox tidy. Unfortunately, somehow I’m receiving emails for many discussed topics. Can someone investigate about this?

The topics I receive are not created by me.

My current settings:

Are you watching these topics by any chances? If you are, then you need to change your notification level to Tracking if you don’t want to receive email notifications.
