Duplicate holiday notifications from Calendar?

[zorinlynx]

Anyone else getting duplicate notifications? I just got THREE banners for Veterans Day when my Mac woke up. While I appreciate honoring our soldiers in arms, that's a bit much.

I only see "Veterans Day" once in Calendar for tomorrow. I don't want to see ANY notifications for holidays, but still want to see them for my actual appointments and events.

How can end this madness??

I also got 3. While I only have a single calendar displaying the holiday, I have 3 calendars on which the holiday appears (2 GMail accounts plus the Apple calendar).
