Duplicate Notifications

I am fairly new to the tool and seem to have set up too many notifications and am looking to minimize these. For example, on a vacation board, I am notified when the item is created - Awesome! I am also notified if the requestor changes those dates, Which happens on every new request, so that gives me a second notification when the item is being created… hmmm, hence starts the problem.

If the person requesting holidays enters the wrong date, and then corrects it, I get another notification.

I just want to reduce the notifications and hoping for some suggestions.
