Google Home broadcast

Configuration
1

Hi

I’am using google tts for broadcast as a script for different functions i my house. Today i changed this script from notify.google_assistant to google TTS to be able to control where it reads my message.
I have one group i google home with the name media_player.overvaning where i normally play internet-radio and spotify and a group named media_player.villan where my message plays.

The problem then, when i trigger this script it first pause media playing and then it check volume on every media_player and store it in input_number. Then it set volume to a little louder an then reads my message. Next this script reset volume to value before the script started and then playmedia that was paused.

Every time this script run, home-assistant create a new media_player with a additional extra number after media_player.overvaning_1 media_player.overvaning_2 and so on. I have controlled my yaml several times and cant find any problem. Have any of you had a similar problem?
The Code:

  media_on:
    alias: Media On
    sequence:
      - service: media_player.media_pause
        data_template:
          entity_id: >
            {% if is_state("media_player.overvaning", "off") and is_state("media_player.kallare", "playing") %}
              media_player.kallare
            {% elif is_state("media_player.kallare", "off") and is_state("media_player.overvaning", "playing") %}
              media_player.overvaning
            {% else %}
              media_player.overvaning,media_player.kallare
            {% endif %}
      - delay:
          seconds: 0.5
      - service: media_player.volume_set
        data:
          entity_id: media_player.villan
          volume_level: '0.5'
      - delay:
          seconds: 0.8
      - service: tts.google_say
        entity_id: media_player.villan
        data_template:
          message: '{{ speak_message }}'
          language: 'sv'
      - delay:
          seconds: 8
      - service: media_player.volume_set
        data_template:
          entity_id: media_player.matsal_main
          volume_level: '{{ states("input_number.media_matrum_2") | float }}'
      - service: media_player.volume_set
        data_template:
          entity_id: media_player.kallare
          volume_level: '{{ states("input_number.media_kallare") | float }}'
      - service: media_player.volume_set
        data_template:
          entity_id: media_player.allrum_uppe
          volume_level: '{{ states("input_number.media_allrum_uppe") | float }}'
      - service: media_player.media_play
        data_template:
          entity_id: >
            {% if is_state("media_player.overvaning", "off") and is_state("media_player.kallare", "paused") %}
              media_player.kallare
            {% elif is_state("media_player.kallare", "off") and is_state("media_player.overvaning", "paused") %}
              media_player.overvaning
            {% else %}
              media_player.overvaning,media_player.kallare
            {% endif %}
