In TB 115.2.2 calendar -- including attendees to newly created events spontaneously adds the creator's email ID to the list of attendees (which it should not do in the first place). When the "Send and Close" button is pressed, the Creator gets a notification (I don't NEED one - I CREATED the event !). But no one else seems to get the notification. Removing the Creator's ID from the list of "invited attendees" seems to solve this problem. But since the creator's ID shouldn't be on the list in the first place, this requires an unnecessary step every time an event is created that involves external attendees, having to remove the spontaneously-added creator's email ID.
