Mqtt double names by Auto Discover

Configuration
1

Hello everyone,
I connect to Home Assistant via MQTT, including Homey. Everything has worked great so far. I have now changed the broker and then deleted the existing broker in the MQTT integration and created a new connection. The devices there are the same as before. However, the name is given twice after the MQTT Auto Discover. As a result, all dashboards no longer work because the entity now has a different name.

Example:
Before the change:
Name: Heating workroom
Entity ID: climate.heating_workroom
After the change:
Name: Heating workroom Heating workroom
Entity ID: climate.heating_workroom_heating_workroom

What should i do?

If you don’t supply a name, the name will be device_id.entity_id. If those are the same, then you get a double.
Change the name in the UI is the best way, Click the gear in the entity screen and you can get there.
Otherwise change either the entity or device names.
