Glance Not displaying column_width

I need help with the code.

I added a glance code and added column_width. Unfortunately, it does not display the code of column_width.

My code:

  - type: vertical-stack
    cards:
      - type: custom:card-modder
        style:
          text-align: center
          --glance-column-width: 16%
        card:
          type: glance
          entities:
            - type: entity-button
              entity: script.back
              icon: mdi:backup-restore
              name: Back
              tap_action:
                action: toggle  

            - type: entity-button
              entity: script.mute
              icon: mdi:volume-mute
              name: Mute
              tap_action:
                action: toggle  

            - type: entity-button
              entity: script.volume_down
