Calendar app and Google Calendar sync = tons of repeated notifications and alerts AFTER event has started

[izzy0242mr]

I sync my Google Calendar to my Mac using the Calendar app and for whatever reason, almost all of the time, events will "magically" get alerts added to them, meaning I get tons of Notification Center notifications even AFTER the event has started. I always swipe them away or click Close—no matter what I do, the problem persists across multiple Google accounts (I have several synced to my computer).

I KNOW I can't be the only person with this issue, but I've posted about this before and no one had any ideas. Does someone know how to get rid of this?

BTW, this happens on two separate Macs (all with the same Google accounts): a 2011 MBP running 10.12.6, and a 2014 MBPr running 10.14.6.

What are the Event Notification settings for those calendars at the Google Calendar web interface?

Apparently the same, but not because they were set to that originally. (This is just an example—other ones are like this too, and it's not just one Google Calendar—it's multiple calendars on different accounts.) I'm pretty sure the Google web event is changing *because* the Mac Calendar is adding these reminders.

I didn't mean the notification settings for a particular event or series of events. I meant what are the settings for the entire calendar. At the Google web interface, if you select (click on) the three dots next to a calendar name, then click on "Settings and sharing", you'll see a multitude of settings for that calendar…one of which is "Event notifications". Whatever the setting is for that will be applied to any new event added to that calendar.

Sorry for the confusion.

Ah, no worries. "Event notifications" has just one item: Notification: 30 minutes

That's it. That's the same for all of my calendars.

Well, at this point I'd probably track down everything, if anything, that I've given permission to access Google Calendar. After that…I can't think of anything.

Yeah that's literally nothing besides my Mac's Calendar app. I am like 99% confident the Mac Calendar app is adding notifications. I think when I swipe notifications away or click "close" it somehow snoozes them and adds reminders to the event entry. And I can't figure out why it does that.
