Why is the Google Calendar website showing my calendar as a guest on events added from the phone? I have noticed a strange behavior in the Google calendar app. When ever I add an event from my phone on a calendar that is not the default one, and later view it on the computers browser, I see a "person icon" indicating a guest. And when I enter that event I see the name of the selected calendar as the guest (technically I'm my own guest).

Is that a result of settings which I can correct? (Or is that a bug?)

I'm using Android 2.3.5
I had the same problem. But it disappeared. I am not 100% sure why, but I suspect that either Android 4.0 (CM9)  fixed it, or the new separately released official Calendar app on Play Store.
