ok, let’s try something else.
go to settings → devices and services (the blue one) → entities
select the right entity
click it and then go to the cogwheel
try giving the entity a name, and if that doesn’t work you could change the entity id. in that case it will display whatever you want. but beware, if you use that entity name in an card, automation, script or something you need to change the name everywhere you used it to make it work again. but that’s logical right?
