Empty Menu for Label Cell Card? (OH3)

Hello,

i am actually migrating my system to the new great OH3.

I created some label cards in main ui and i am wondering about the 3-dot-options menu:
When i click on the card, the group items open as aspected, but when i click the menu, a blank layer opens.
Can you tell me, how to use/deactive this menu?

component: oh-label-cell
config:
  header: Wohnzimmer
  item: WZ_Licht
  action: group
  actionGroupPopupItem: WZ_Licht
  icon: f7:lightbulb

I found a solution to remove the dots right here:

But what do these dots usually do?

Hi,
“But what do these dots usually do?”

You can add content by filling the slots: like this for example:

component: oh-label-cell
config:
  item: Presence
  header: Who Is
  title: Home
  action: group
  actionGroupPopupItem: Presence
  icon: "f7: person_3"
  trendItem: Presence
  expandable: true
slots:
  default:
    - component: f7-row
      slots:
        default:
          - component: oh-image
            config:
              url: https://picsum.photos/600/300
              style:
                width: 100%
                height: auto
