Unifi Hub: ssid_filter not working

Hello community

Whatever I do, the ssid_filter in the unifi component doesn’t work.
I have two SSIDs, one for the Clients and one for IoT devices. Even if I filter the IoT SSID, I still see my normal device.

unifi:
  controllers:
    - host: 127.0.0.1
      site: NAME.private
      ssid_filter:
        - 'SSID.IoT'
      dont_track_wired_clients: true
    # detection_time: 360

Everything is :latest and based on Haper-V and the hass.io:2.12 image.

Any ideas?
