A named non-attending ticket is not zero tickets

In GiveCampus Events, available controls depend on your assigned administrator role(s), access to the event, and the interface used by your institution.

The standard package UI offers 2–50 tickets. An individual ticket still creates an attendee/ticket; calling it Non-attending, hiding it or making guest fields optional does not create a zero-ticket sponsorship. Add-ons belong to a Complex-event registration, not an independent purchase without registration. Review a separate giving form for sponsorship-only contributions or have event support design the required benefit/attendance workflow. Do not repeat the unsupported workaround that an individual ticket represents zero attendees automatically.
