yup they are all syncedDid you check in Settings > Accounts & Sync to be sure they are all set to sync?
Just an idea, but go into Settings > Applications > Manage applications > All tab > I have both Calendar and Calendar Storage... I think you should open both and click the Clear data button on both... then go back into Accounts & sync and sync all.
I've used the "Clear Data" button on "Calendar Storage" app a couple of times when the calendar entries seem to have gotten out of sync. No ill effect other than the next sync takes longer because it has to download all of the calendar entries again. I'm not sure what clearing the data for the "Calendar" would do since I don't use the stock calendar, but I'm guessing it would just reset the settings unique to the stock calendar app.
