Google Calendar delegates being listed twice
About two months ago this problem started happening. I have several google calendars that I access with MacOS Calendar (Mountain Lion).
As usual, the main calendar shows up under "GMail" in the sidebar and all the other sshow up under "Delegates". But recently, all the calendars in delegates have also been showing up under "GMail", creating duplicate event entries in the calendar view. This happens intermitently. It will just appear and disappear periodically. Everytime it happens, I need to unselect all the calendars under 'Gmail' so I don't see the duplicates, then after a while they will disappear altogether, then reappear later, selected.
Anyone else seeing this? Any solution?

p.s. I find the Google calendar support pretty flaky in general. Get a lot of server errors here and there, and find the whole way "delegates" to be handled is very cumborsome, curiously much more complicated than in calendar.google.com.
