Receiving "Daily email send notification" multiple times when only one should be sent

Hi guys,

Got a bit of an issue where I keep getting these emails, for example my limit is set to 50 in tweak settings, although had a customer today send just over 50 emails, but I received 10 copies of the warning email?

I immediately thought woah they sent 500 emails, but nope, just over 50... why did I get ten copies of this email?

Has happened on several occasions too!!

All other cPanel notifications only come in one time like normal so this is a bit odd
