Problem with Alexa Media Notification and Google generative AI ("back slashing")

When I write any automations using Google Generative AI (response variable) and Alexa Media Notifications, the echo starts by first saying “text” prior to the message, then repeatedly adds (“back slash”) or (“back slashing”). Usually tts and Alexa media doesn’t first announce as “text”. No clue where the black slashing comes from. When testing the prompt it doesn’t show any characters or anything that would be spoken as “back slashing” when I manually test the prompts action then paste the response instead of using {{response_variable}} its spoken just fine. I’m not certain why this happens and how to correct it. I certainly don’t want to hear text before each notification or Alexa say “Back Slashing”.

  - trigger: zone
    entity_id: person.sarah
    zone: zone.home
    event: enter
conditions: []
actions:
  - action: google_generative_ai_conversation.generate_content
    metadata: {}
    data:
      prompt: >-
        Welcome Sarah back home. Be friendly and sweet. Do not not worry about
        language, being PG or SFW. Give a short response in clean text with no emoji's symbols, unnecessary characters or formatting.
    response_variable: welcome_response
  - action: notify.alexa_media_bob_b_echo_dot
    metadata: {}
    data:
      message: "{{welcome_response}}"
      data:
        type: tts

I’m kinda guessing that the welcome_response actually contains some garbage text and several backslashes. Maybe try {{ welcome_response | replace("\\","") }} just to see if it helps the backslash part.
