DIYHue for Ambilight - no Lights to choose when trying to create an Entertainment Area

Hello all,

I am trying to create a DIY Ambilight which I cannot create at the moment because in the hue app, I cannot choose any light in the entertainment area.

I am running the DIYHue Home-Assistant integration on a Raspberry pi 4.
I am able to add the lights to the philips hue app and controlling them also works.
But when trying to create an entertainment area for the TV no lights are shown to create the ambilight.

Currently I have two ESP8266 set up while one is running the SK6812_v2 firmware and the other one is running with the WS2812_v3.1 firmware both flashed from install.diyhue.org

Thank you in advance!
