Calendar broken

I have been unable to create repeat calendar events over the past 3 weeks without the app freezing. Please fix this glitch. I really like using this calendar but will need to switch if it is not updated this week. Also, I have tried to delete the app and reload but have lost past and recurrent (future) calendar entries. This is really frustrating!
