Deleted iCloud email aliases are still showing under my Apple ID
I've just been able to switch to 2 Factor Authentication and after signing into the new look Apple ID manger page that comes with it all my previously deleted iCloud email aliases are listed along with my main email address as address I can be reached at. I can't see any way to deleted them. There's about eight of them altogether and I don't have any of them currently in use at all (i.e. they've all been completely deleted from the iCloud.com email preferences).
Anyone else noticed this, or know a way to get rid of them?
iPhone 6s, iOS 9.1
