Cannot do entities configuration

Configuration
1

Hello,

I have just configured my Echo device to work with Home Assistant and all my devices are correctly discovered, but I am not able to customize them (name, filtering out some devices).

This ispart of my conig.yml:

   >      cloud:
>           alexa:
>             filter:
>               include_entities:
>                 - climate.danfoss_z_thermostat_014g0013_heating_1
>                 - media_player.denon_avrx400
>               exclude_entities:
>                 - climate.danfoss_z_thermostat_014g0013_heating_1_2
>             entity_config:
>               media_player.denon_avrx4000:
>                 name: denon
>                 description: Denon in livingroom
>                 display_category: SWITCH
>               climate.danfoss_z_thermostat_014g0013_heating_1:
>                 name: kitchen thermostat
>                 description: Thermostat in the kitchen
>                 display_category: THERMOSTAT

Whatever I do in the config, it looks like it makes no impact on Alexa Smart Home skills. Devices are still being discovered under their original names.

Anybody had the same problem?

This is what I can see in the logs, when doing device discovery on Alexa App:
