This is the only way that I have been able to fix this problem.
First, go to the calendar.
Now up at the top, click VIEW and then CURRENT VIEW. You may have to choose
ARRANGE BY depending on your version. Now select RECCURING EVENTS.
You will want to write all these down or just take a screen shot so you can
enter them in later. After that, you want to delete all the recurring events.
Then comes the fun part, re-entering all the events. Should work after that.
Hope that helps. Its the only work around that I know of.
