Can't disable alert emails

I’ve tried to disable alerts for a project, but am still receiving them. Both the main toggle as well as the project under “fine tune by project” are off—I’ve even tried turning all projects off—but am still getting emails.

The footer of the email says “You are receiving this email because you have opted to receive updates for all issues within projects that you are a member of.”, which is not true given the settings I see. Am I missing something?
