I experienced the same. On iOS 5.0 it actually seems like the calendar is also used for reminders automatically.
You need to delete the calendar from the reminders app.
I think it may be a bug in iOS that you don't even get a notification when you unsuccessfully try to delete a programmatically created calendar from the calendar app.
