Items added to GCal do not appear as the proper unavailable time on the Appointments + web interface

I have GCal set up to sync both ways with Appointments +. I have a bunch of events in my GCal that I added through GCal, but the times they block off on my website are not the same times as they are in GCal. Only items scheduled through Appointments + display the proper time as unavailable. Any ideas of what I'm doing wrong? Website is Thanks!
