Disappearing Appointments
 

I'm having a problem that I'm sure there's an answer for somewhere here, but I can't find it.

All my yearly recurring appointments aren't showing up in either the stock calendar app or Pocket Informant. In the day, and week view, I see them, but when I switch to the month view, they disappear. I've made sure there are no filters on, so I know it's not that either.
