Automations not showing in GUI

Hi all, my first post so please go easy! I’ve only been trying HA out for a couple of weeks.
I have an issue where I cannot add any automations apart from one I added a few days ago (auto backup config each night).
When I add an automation in the GUI and save it, it does not show in the list. However, it does drop in to my automations.yaml file.
If I drop both automations from the YAML file, the nightly automation still shows in the GUI. If I swap them around so my new automation is at the top of the file, still only the nightly automation shows.
What is going on here?

configuration.yaml

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

automation: !include automations.yaml

scene: !include scenes.yaml

Hi, welcome to the forum!

Have you refreshed your browser / cleared the cache / tried with another browser?
Did you read this: Splitting up the configuration - Home AssistantExample: Combine !include_dir_merge_list with automations.yaml

Are you sure that this is correct?
Could your automation be disabled - and due to some active filters in “Automations” list you cannot see it?

ALso, check this:

Thanks all!
I did all sorts to get this working. In the end I just rebooted and it all started working normally.
I have no idea what happened but thanks a lot for the replies!
