Cancelling an Appointment Sends Confirmation

I've been doing a lot of testing to get email working and noticed something in the appointments "pending" section.

When I choose "remove" from the dropdown to update an appointment status and check the (re)send confirmation box. The customer gets an email confirming their appointment is still good to go.

Logically I would expect a "removal" or "appointment cancelled" email to be sent given that I just selected "remove" from the drop down.

If a service provider needs to cancel an appointment that a customer made, there should be an easy, built in way to do that, right?

Maybe I'm missing something? Not sure if this should be classified "bug" or "feature request"?
