iCloud Shared Calendar Duplicate Alerts

[ThatTechGuy]

My sales team and I share an iCloud calendar that we update many times throughout the day. Someone will add an event, perhaps two hours later someone will edit it, the next day someone else edits it, etc. We have events scheduled for many months in advance. When someone edits an event, I get an alert that the event has been updated. That's fine, and as it should be.

However, my issue is that let's say Person A edits an event. I get an alert. Then Person B edits the same event. I get a notification that Person A edited the event as well as a second notification that Person B edited the event. It continues as each new person edits to the event. It's gone all the way up to four individual notifications when Person D edits the event, I'll get new notifications for A, B, and C.

Any ideas on how to make this stop?

Thanks
