Handle entity exceptions in stories

Hi, so I am playing around a bit by building a pizza bot. I want to handle orders but train my bot so when the entity “Peperoni” for pizza_type is recognized, the bot should utter something different. For all the other values the bot should utter the standard response. pizza_type is configured as type text. But somehow the bot answers the peperoni utter to all my requests. What am I doing wrong?

    ## place order
    * order
      - utter_order_pizza

    ## place Peperoni order
    * order{"pizza_type": "Peperoni"}
        - utter_no_peperoni
