MQTT connected count is off

So on version 8.1.7 I have two transmitters created inside of on MQTT set, but when I look at the server it shows a value of 0/3 (it is currently disabled) why do we have 3 now instead of two?

When I have one transmitter it shows a 0/1 count.

Also if I set up a third transmitter it will keep the count at 0/3.
