Adding/removing holidays on calendar

[jmhultin]

My main calendar has holidays marked. I created a second calendar "Home", and wanted to add holidays. I hit File/Options/Calendar/Add holidays and now it duplicated all holidays on my main calendar (way into the future!) and added no holidays to my Home calendar.



The Undo button doesn't work. How can I remove the duplicated holidays, and add holidays to my Home calendar?

Thanks
