Best Practice for using AppointmentStore.StoreChanged in UWP app

I develop a Calendar app for Windows 10 and I have been looking into using the AppointmentStore.StoreChanged API. During my testing I found when an Appointment is added to the AppointmentStore the Changed event fires 4 times. First for AppointmentCreated event then three more times for "AppointmentModified"

Why might this be happening? Is there a way to improve my usage of AppointmentStore to get a single AppointmentCreated when adding a single Appointment to a calendar?

I have created an AppointmentService to keep a single instance of the AppointmentStore in my app, but I still get multiple events when adding a single Appointment.
