I apologize for any confusion there may be with this contact that is set to awaiting confirmation. I took a peek and can see they have previously unsubscribed. Through our resubscribe process, your contact will receive a Confirmed Opt-in email where they will need to click a link in order to confirm their interest. As soon as the contact clicks the link in the email, they will be added back to the lists you've selected. Until this happens they remain in awaiting confirmation.
