You can manage events from Settings >> Events.
1) Only the event name set at event setting is displayed on the screen.
Results are summed for events set with the same event name including manually set events.
2) For those events that have been set manually, “successfully set” is displayed as “set up.”
Events that failed to set are displayed as “Not set.”
Events that you set manually can not be deleted in Overlay heat map, but you need to delete it from the code.
3) If only one event has been set, details of event setting information will be displayed
