Missing or vanished recurring meetings!

I think the same thing happened to me. We schedule meetings a year in advance. I used to be able to see all future scheduled meetings in the meetings list. Now there is a range of only one month and it doesn't include all meetings in that month, only the very next meeting. We have a number of subcommittees starting up and I need to advise people when are the best times so they don't want a meeting scheduled that interferes with another meeting. There is a ? bubble on the meetings list in the calendar range box, and it says. "If you want to see more meetings, you need to update your calendar range." Then there is an calendar icon and clicking on that gives me a calendar pop up. I tried to make changes in the pop up, BUT THERE IS NO WAY TO SAVE CHANGES! I do not keep a calendar on my computer, nor do I want to for security reasons. Does anyone know how I "update my calendar range" ??? Thanks. I work for a radio station.
