Registrant Counts field names confusing/misleading

[dwhitig]

The registrant counts section fields are labeled as Attendee counts but they are actually registrants counts as they are all actually the total registrations: Roll-Up Summary (SUM Summit Events Registration) which could be confusing and the filter criteria cannot be changed as it is a packaged field. Consider changing the wording for new installations? Not sure how this would impact the documentation and existing installs but thought worth bring up.
