Duplicate Safari Push notifications

[Reason077]

I have an issue where a particular website (cityam.com) is constantly sending me duplicate push notifications. Every notification is duplicated 4 times - see screenshot below.

Obviously I can block all notifications from cityam.com, but I do actually want these notifications, it's just that I want each notification once, not 4 times!

Is there a way to actually unsubscribe and re-subscribe to a website's notifications, rather than just blocking it in Safari's notification preferences? Failing that, is there a way to completely reset Safari's push notification system, so that all existing subscriptions are deleted and I can resubscribe to the ones I want manually?

Having the exactly same issue... Very annoying, but I really need the notifications, and they pop up each 2-4-6 minutes, the same, same one.. Very annoying, and not finding anything helpful on google.

If you find a way to sort it, Ill appreciate if you can share it please! Kind Regards!
