Yep. I saw that bug when I was working on v2.0 the other day.
At the moment, it will find all events in the categories you choose – that’s the 30 events it tells you about. But in the iCal feed, it only includes up to the number of events you specify and the number of weeks to look ahead.
Just change the number of weeks, days, years to something large.
It’s only a small bug ??
