CC's not showing up when I reply to a ticket

I am using version 3.6.5

I have tickets that have CC;s listed on them.

I have the scripts enabled for NotifyOtherRecipients and
NotifyOtherRecipientsAsComment

But when I hit reply they email address is not listed below as available…

I have a script for notify owner on correspond and that email is
listed but not the CC’s is there a permission issue I need to have in
order for it to work…

Thanks/
