Picture-elements card problem

I have this card:

      - type: picture-elements
        image: /local/floorplans/Floorplan2.png
        elements:
          - type: service-button
            title: Luci On/Off
            service: light.toggle
            service_data:
              entity_id: group.all_lights
            style:
              top: 2%
              left: 50%
              padding: 1px
              font-family: Ariel
              font-size: 200%
              font-style: italic
              color: red
              font-weight: bold

But in the frontend i always get this:
00
Regardless if i change every option in style.
Is it a bug or my fault in something?

you’re refreshing the browser cache right?

Yes, i did it many times…
