HA ignoring yaml changes or applying wrong setting

Hi there,
I am just starting to configure HA but it seems than HA is ignoring the yaml parameters or applying wrong ones. I am now configuring the light. First I did directly in configuration.yaml. After saving the file and restarting I found at some light were working like expected, some were taking parameter values different than the ones configured, some were taking the right parameters but not working, other just ignored and not showing in the Overview. Suspecting a cache error I split it and include a ligths.yaml in configurations.yaml but to no success.
I am using HAOS on a Raspberry Pi 4, working fine found many of my connected devices. Some of the light are connected with a Philips Hue gateway, it does not require yaml configuration and are working fine. Other are connected using a HACS installed pluging, anotherjulian Myhome, and require yaml. To the best of my understanding it seems to be a HA issue, not the MyHome issue. No error in the log. Any help welcome
Here my configuration.yaml and my lights.yaml

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

# Text to speech
tts:
  - platform: google_translate

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
light: !include lights.yaml

lights.yaml looks like
