Nokia :: 5230 Calendar Events Notifications Error?

I am using the Nokia 5230. I have noticed a strange thing . When you set the option as 'contacts bar' in your home screen settings , one is unable to see any calendar events (anniversay, to-do) on the main screen.However when you switch off the 'contacts bar' in the home screen settings , you can see all calendar events appearing on the screen.What is the reason for this ? I as a use would always like to see my calendar events on the homescreen. Is there anyway I can see the contacts bar as well as the calendar events both appearing on the home screen together.
