Lights not showing as dimmable in Alexa via haaska or Home Assistant Cloud

I’m trying to get my devices working with Haaska correctly. Right now, I have it setup and all my devices show up, but the groups only show up as on/off (switches?) as opposed to dimmable (lights?) in Alexa. They show up correctly in hass though. I am currently using haaska, but I had the same issue when I tried home assistant cloud as well. Here’s my current code:

  alexa:
  smart_home:
    filter:
      include_entities:
        - group.bed_room_hass
        - group.great_room_hass
        - group.down_hall_hass
        - group.kitchen_hass
        - group.stairs_hass
        - group.up_hall_hass
    entity_config:
      group.bed_room_hass:
        display_categories: LIGHT
      group.great_room_hass:
        display_categories: LIGHT
      group.down_hall_hass:
        display_categories: LIGHT
      group.kitchen_hass:
        display_categories: LIGHT
      group.stairs_hass:
        display_categories: LIGHT
      group.up_hall_hass:
        display_categories: LIGHT

If I remove the entity_config section, I just get houses with a wifi symbol, and can’t actually do anything with them. Anybody know what else I need to do to get them dimmable? On/Off works fine from the alexa app and voice.

I did try posting in both discord and the homeassistant subreddit to no avail. Hopefully someone here can help me out.

TIA!

Any luck figuring this out? I have same issue.
