Bugs with calendars

Most of the calendars have multiple entries (Calendar, Tasks, Holidays, etc.), all have multiple entries in the hide/show preferences dialog). Why? Makes no sense.

Hiding calendars works, but you have to click on a different day and then click back to see the changes. If any calendars have the same name as other calendars (which, working in an office with Outlook, everyones calendar is named "Calendar"), they all are considered to be the same calendar by Opus Domini, so nothing works right.
