Alexa, entity with wrong name

I had an Echo dot configured on my home assistant without any problem.
I bought another Echo dot and the smartphone configuration in the installation of the new device put a name (‘2o echo dot de jose’) that afterwards, I changed it to ‘echo dois’.
In my home assistant all entities appear as ‘.2o_echo_dot_de_jose’ and not as ‘.echo_dois’.
I tried to restart the home assistant, the host, but nothing worked.
How can I change or update my entities to the correct name?

I’m using Home Assistant 0.117.6. Frontend version: 20201021.4
