Covers cannot continue moving after stop

Hi there,
simple question about the shutter config.
My HA is driving the shutters but if i press Stop during the shutters are moving down, i cannot continue after that. That means, the down button is grey. I have to press “up”, then Stop and then down again… (same in the other direction).

the yaml code is:

  - name : "Wohnzimmer"
    move_long_address: "2/1/0"
    stop_address: "2/2/1"    

Does anyone know the reason?

No one knows the reason?
