Calendar Invites and @icloud

Ever since I have had an @icloud alias added to my account I have been unable to send or receive icloud calendar invites on iPhone, iPad or Mac.

People are able to send to my @icloud address and they show up as notifications, however when they are sent to @me I only receive an email invite.

Every invite that I send to other icloud users does not get received..

Also I have noticed that when I create an event they are all tagged now showing Created By/Edited By and then linking to my contact card.

None of this happended before the aliases showed up. I have tried turning off iCloud on all devices but still not working.

Any suggestions
