Mushroom Chip doesn't respect device class and language

Hi,

I’m using mushroom (newest version, 2.7.1) to display the state of a door.

The yaml is

type: custom:mushroom-chips-card
chips:  
  - type: entity    
    entity: binary_sensor.lumi_lumi_sensor_magnet_aq2_opening

The rendering, however, only shows “on” or “off”, and neither “open” / “closed” nor the respective German translations. I’ve set the general language to German, as well as the user language. In standard lovelace-ui, this works fine (screenshot below), so I suspect it’s a mushroom problem. But apart from re-installing (which I did), I don’t know where to look or what to try.

Any ideas?

The solution was a browser-cache issue. After emptying the browser cache and reloaded the page, it worked again.
