Can I use the new conditional response variation feature within a form?

Hi all,

I tried to use conditional response variation within a form (Rasa 3.1) but for some reason it does not work. Now I am wondering whether I did something wrong or whether conditional response variation within the domain.yml is not meant to be used within a form?

This is my implementation:

DOMAIN:

intents:
  - rate_food
  - rate_color
  - rate_drink

entities: 
  - food
  - color
  - drink


responses:

  utter_ready_flow_form:
  - text: "Ready for the flow form?"

  utter_ask_flow_form_food:
  - text: "Which has more delicious pizza, pasta or rice?"

  utter_ask_flow_form_color:
    - condition:
        - type: slot
          name: food
          value: "pizza"
      text: "You said pizza. What is nicer green, red or yellow?"
    - condition: 
        - type: slot
          name: food
          value: "pasta"
      text: "You said pasta. What is nicer green, red or yellow?"
    - condition: 
        - type: slot
          name: food
          value: "rice"
      text: "You said rice. What is nicer green, red or yellow?"
    - text: "You said something else for the food question, that is the default answer."

  utter_ask_flow_form_drink:
    - condition:
        - type: slot
          name: color
          value: "green"
      text: "You said green. What tasts better, tea, coffee or milkS?"
    - condition: 
        - type: slot
          name: color
          value: "red"
      text: "You said red. What tasts better, tea, coffee or milkS?"
    - condition: 
        - type: slot
          name: color
          value: "yellow"
      text: "You said yellow.  What tasts better, tea, coffee or milkS?"
    - text: "You said something for the color question, that is the default answer."

  utter_reached_end:
  - text: "It has worked"


slots:
  food:
    type: categorical
    influence_conversation: true
    mappings:
    - type: from_entity
      entity: food
      conditions:
      - active_loop: flow_form
        requested_slot: food
  color:
    type: categorical
    influence_conversation: true
    mappings:
    - type: from_entity
      entity: color
      conditions:
      - active_loop: flow_form
        requested_slot: color
  drink:
    type: categorical
    influence_conversation: true
    mappings:
    - type: from_entity
      entity: drink
      conditions:
      - active_loop: flow_form
        requested_slot: drink


forms: 
  flow_form: 
    required_slots: 
      - food
      - color
      - drink

STORIES:

stories:
- story: happy path flow form
  steps:
  - action: utter_ready_flow_form
  - intent: affirm
  - action: flow_form
  - active_loop: flow_form
  - active_loop: null
  - action: utter_reached_end

Would be great if someone could point me either to my mistake or explain why conditional response variation does not work within a form!

Many thanks!
