Google Calendar showing other users events?

Hello!

I am trying to get Google Calendar Integration working and I was able to get it going with these instructions, but its not showing events from my calendar, its showing events from other users calendar? Whats happening and how do I fix that?

These are not mine

Thanks
Zac

This is a huge deal to us Google, what if when the next time this happens an Exec has some sensitive information in his calendar that gets replicated to an interns calendar?
