Unable to delete event in evolution calendar

I want to be able to delete obsolete or changed events and recurring events. My calendar is currently littered with cancelled events and cancelled recurring events and changed events where I could not delete the old events. There are no menu options for deleting an event. A calendar that does not have an option for deleting an event is "NOT READY FOR PRIME TIME".

Creating a new calendar does not solve the problem.

I am not an expert user so if it involves using the terminal program, cut and paste is best as I do not wish to do something that would require a clean install.

I am using Ubuntu 10.10 with all the latest updates with very few modifications, so it should be close to the default. I do not plan on going to a different version until the next long term stable release becomes available.

I would appreciate it if you could include the instructions for deleting the entire calendar or even the entire evolution package if there is no way to delete recurring events and single events.
