Showing Registrants

When I create a new event, I have some events whereby we do NOT allow online registration. One of our sub admin people add the players to these events from a member list that we created. What the problem is, that if I don't click the "Allow Online Registrations" it won't permit any of those who get added by the sub admin person to be shown as a registrant. It appears that the "Show Registrants" is not able to be click without the "Allow Online Registrations" to also be clicked first. I understand there is not a way to show registrants, unless the Allow Online Registrations is checked? Can you please allow this?
