Switch names don't get saved

how you rename? post your yaml file have a look.

I just did the first 8 in the GUI, checked the YAML and no change there.  While in file editor I changed the last 8 as pasted.  I restarted just the YAML portion in HA and no change in YAML or GUI. I then restarted HA and lost all changes done in GUI and in file editor to YAML. Yes, I saved changes in file editor before closing and restart of HA.

Posting entire config yaml.  Im very sorry to have bought this device,  not good vale and costing me too much time now.

Code:

# Loads default set of integrations. Do not remove.
default_config:

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

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
