Issue with light groups

Configuration
1

Hey

I have a Raspberry Pi 3 running Hass.io and an Conbee. My problem is when i use light groups, and call an entity, it will turn on every entity in the light group.

my configuration.yaml

light:
  - platform: group
    name: dimmer_01
    entities:
      - light.spisestuen_loftlampe
      - light.gangen_loftlampe
      - light.mellemgang_loftlampe
      - light.legehjornet_loftlampe
      - light.trappen_loftlampe

When i remove the code above from my configuration, the light acts normal and only turn on the entity theres called.

Anybody got a solution for this problem?
Thanks.
