Hi, I"m having trouble moving all the people who have opted out of my emails to a master opt-out target list to suppress for future emails, I go to select all those who have opted out of a list to add to a target list, but it seems like nothing happens, as the target list I select is empty, none of the names I move over are populating. This is an important issue because I need to ensure that all those who opt out of our emails, are truly opted out and will not receive any future emails from us..... help needed, thanks.
