Renaming Entities from Configuration.yaml

Configuration
1

Hi, i added some utility meters in configuration.yaml and tried to rename these after using them for a couple of weeks. But now i get the problem that they didn’t receive the new name but instead just the old with _2 at the end.
is there a way to rename these or delete these?
I am running HAOS in a Proxmox VM.

some of my utility meters:

I just had a similar experience. It really left me scratching my head.

I changed the Entity ID’s for 4 Scripts and the changes seemed to take but the old entity ID’s continued to show up when referenced in a dashboard button. I ended up editing the /homeassistant/scripts.yaml file to erase the old Entity ID’s and replace them with the new Entity ID’s.

Not sure why the changes that I made were not propagated through the system automatically. But it’s ok now.
