multizone thermostat turns off the heater, even if other zones actual temperature is still lower than its "target_temp_sensor"

Describe the bug

Hi,

Firs have to thank you, great addon you have created here, but somehow it is not working as expected.

You see in my config bellow I have 3 zones. when I put all zones "target_temp_sensor" above their actual temperature, heating is on as expected, but when I then set just one zones target_temp_sensor" below actual temperatur, the multizone thermostat turns off the heater, even if other zones actual temperature is still lower than its "target_temp_sensor".
Also perhaps worth to mention: After setting first zones target temp below the actual, I see in the mz-thermostat card, that I gets a new target value, but still turns of the heater like stated.

I created a small video to visualize the behavior: https://i.imgur.com/1O8oGtr.mp4

Whats the problem here?

Thanks in advance.

Cheers Thomas
