Spent 2 hours with tech support today, trying to chase down why scheduled activities filtered by type, didn't show up on Activitiy Lists. After re-indexing, trouble-shooting, etc., we discovered that even though events show up on the Calendar as scheduled, if they are recurring activities, they don't show up on the Activity report. Therefore, if you need to have recurring items show up on an activity report - the only way to really do that is to NOT use the recurring appointment, and key in recurring activities individually - as if each was a stand alone event. I frankly think this is a bug, but discussions with Tech ended with this being the way the system was designed. It would certainly be much more powerful if once scheduled as a recurring event, the activity would show up in all the other places (in the activity tab in the contact, on activity lists, etc.) and not just on the Calendar.
