Group Ordering Messed Up

My groups are not displaying in the correct order. Here is how the group is defined:

  default_view: 
    view: yes  
    icon: mdi:home 
    name: "Home View"
      - group.house_summary
      - group.indoor_light_summary
      - group.outdoor_light_summary
      - group.scheduled_items

The displayed order is:
house_summary
outdoor_light_summary
scheduled_items
indoor_light_summary

I tried adding some group order options in my customize.yaml, but that did not work either. This was not a problem in the past, this used to show up in the correct order.

customize.yaml entry:

  group.house_summary:
    order: 1
  group.indoor_light_summary:
    order: 2
    emulated_hue_hidden: false
  group.outdoor_light_summary:
    order: 3
    emulated_hue_hidden: false
  group.scheduled_items:
    order: 4
