Appointments + showing duplicate appointments in "Reserved By GCal"?

I have a site with 1 service provider set up and the Appointments synch well to google calendar, however for some strange reason I see duplicates off all my appointments made in Appointments + in the "Reserved By GCal" part of the site. It doesnt seem to cause any error and the Google Calendar does not show them however I wanted to inquire before it becomes a problem if it does. Thank you.
