People Opt-out Emails Duplication

I was reviewing the People | Opt-Out Emails from the Home Screen this morning and noticed that there are numerous double entries (as pictured). I likely have misconfigured something or even possibly listed the option in two different locations during account creation and/or checkout.

Has someone else experienced this?

I don't know why that is. If someone opts out and clicks the link again to opt out, it checks to see if that email is already on the list and won't add it twice. I just tested it out and I can't get an email added twice. 

I see that they are a minute or so apart which makes it more strange. I really have no idea.

do you have more than one email listed in the admin?

That is an intriguing question Vance. Sort of, see attached.

Well the only way to test this theory is set up two dummy accounts and two email accounts. Then test as is and then test without that second email in admin.
