My Home Assistant version: 2021.09.7

Fold-entity-row version (FROM BROWSER CONSOLE): 20.0.12

What I am doing: Trying to set head inside a auto-entities group filter

What I expected to happen: entity shows up with secondary-info in the head

What happened instead: secondary-info isn't showing up. the entities inside the group are showing up with the right state but without the secondary info

Minimal steps to reproduce:

# The least amount of code possible to reproduce my error

type: custom:auto-entities
card:
  type: entities
filter:
  include:
    - group: light.downstairs
      or:
        - state: 'on'
      options:
        type: custom:fold-entity-row
        head:
          entity: light.downstairs
          secondary_info: last-changed
        group_config:
          secondary_info: last-changed


# End of code
