I cannot uncheck Holidays in United States and thus I can no longer see my events?
I have been having a problem of Synching my Macbook Pro Calendar and while search for a solution I opened Window on the toolbar. I noticed "Holidays in United States" was not checked so I checked it. Now my Calendar only displays holidays and no events. I tried unchecking it but it will not let me.
When I Quit Calendar and reopen it opens with all my events and then quickly reverts to the Holidays in the United States calendar and I can see nothing else.
There is no list along the left side. I am operating with the latest release of El Capitan.
