Date and Time added to configuration.yaml - not showing in frontend?

I followed the information on Time & Date - Home Assistant and added the following to configuration.yaml (this is the only “sensor:” in that file)

sensor:
  - platform: time_date
    display_options:
      - "time"
      - "date"
      - "date_time"
      - "time_date"

I used the Studio Code Server add-on but I also checked it using SCP/SSH and the entries are there - I reloaded the config and even rebooted. When I try to find any of the entities in the frontend, they simply don’t exist. Am I missing something obvious to get them to show up?

Are you sure you have edited the same configuration.yaml file that HA is reading?

config/configuration.yaml

That’s the only one I have. Here’s the full file as viewed in Studio Code Server addon:
