Mushroom cover card stop button locks other buttons

Hello everyone,

before reporting a bug to lovelace-mushroom, i want to understand whether i have a frong configuration on my end.

Current setup: HassIO on rasp 3 B+
configuration.yaml:

`cover:
  - platform: template
    covers:
      roller_shutter_soggiorno:
        device_class: shutter
        friendly_name: "Tapparelle soggiorno"
        open_cover:
          service: script.su_soggiorno
        close_cover:
          service: script.giu_soggiorno
        stop_cover:
          service: script.stop_soggiorno   
      roller_shutter_studio: ecc...

this properly created a cover entity, wich i included in mushroom “cover card”.
Works properly for up and down buttons, updates icon as well. Stop button triggers script correctly but it retains the last button pressed, I.E. i press down, stop, down button cannot be pressed again because it’s stuck. The card by default does not allow me to press the same button twice, but i would expect that hitting the stop button reset the other two buttons. Is this an issue on my configuration or is this a bug on mushroom card?
