I'm Getting Safari Notifications I Don't Want

FIRST things first, Malwarebytes is the first thing I ran and I'm clean as a whistle. I also have no weird profiles or safari extensions here. But despite that, I'm having notification problems.

So I ALWAYS say no when a website asks for permission to send notifications. This would NEVER be the kind of thing I'd be interested in and I would never say yes to any website. Send me email notifications if you want to say something to me.

And yet somehow, if I go into Safari Prefs > Websites > Notifications, there are TONS of "Allow" settings!

And what's more, the list of sites is a mile long, theres probably thousands of sites in the list. Way too many to go through one by one.

And if I try anyway, after one or two "Remove"'s, safari crashes. It does this every time, completely repeatable.

Is there some way to remove EVERY site from that list, easily? I already unchecked "Allow websites to ask for permission to send notifications", but now I need to clean out the existing mess.

I would also LOVE to know how all these websites "allowed" themselves when I know for a fact I've said no to every single one.
