Custom Icons not reflected to Picture Elements

I am trying to get several window-contacts to be displayed within a picture elements card. I exported a floor plan of my house to a PNG file and I would like to put a specially colored Icon next to each window, when it is open.
The window-contact switches are included via phoscon and are displayed as binary sensors. This is the way I included them into lovelace:

type: picture-elements
elements:
  - type: state-badge
    title: Fenster
    entity: binary_sensor.fensterkontakt_hwr
    style:
      top: 80%
      left: 22%

This renders nicely to this:

Also it is clickable to show the last states (which is what I want). I tried to change the Icons as well as the color globally for all of this sensors like this:

configuration.yaml:


# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
#entities: !include entities.yaml

homeassistant:
  customize_glob: !include customize_glob.yaml

customize_glob.yaml:

"binary_sensor.fenster*":
  state_icons:
    "off": "mdi:shield-home"
    "on": "mdi:lock-open"
  state_styles:
    "off":
      color: green
    "on":
      color: red
"binary_sensor.tur*":
  state_icons:
    "off": "mdi:shield-home"
    "on": "mdi:lock-open"
  state_styles:
    "off":
      color: green
    "on":
      color: red

This seems to be working but is not actually shown in the frontend. Why is that? Am I making a simple mistake?
