Automation calls scene but then does extra things

I have some weird behaviour that I am hoping someone can help me with. I have a zigbee wall switch and 6 x RGBW GU10 bulbs. There are also 3 x Govee LED strips that are part of the scene but are not part of the problem.

When the first switch of the Zigbee switch is in the on position, it triggers an automation that calls a scene called cinema_blue. This scene should set all six GU10 bulbs to blue. When the switch is turned on all the lights go blue, but then all go white. I don’t understand what is making them do this extra step as there is nothing anywhere that can make this happen as far as I can see.

Here is the automation:

  • id: ‘1646602942853’
    alias: Cinema blue
    description: ‘’
    trigger:
    • platform: device
      type: turned_on
