Registration closure versus registrant editing

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

In event Ticketing → Registration Edits, turn off Allow registrants to edit their initial registrations to restrict the enabled registrant edit flow. For complex events the enabled setting allows adding activities/add-ons and removing free items; paid removals do not trigger self-service refunds. New-registration closing dates are separate. Review the two actual additions, actor and activity availability to explain why those closed activities were added; changing the setting does not mean the cause of past activity.
