About the story's format

For example, My story is about the status of a user’s order. It likes this:

  • ask_order

    • reply_order_list
  • confirm_order_number{“order_id”:“1”}

    • reply_order_status
  • ask_order

    • reply_order_list
  • confirm_order_number{“order_id”:“2”}

    • reply_order_status
  • ask_order

    • reply_order_list
  • confirm_order_number{“order_id”:“3”}

    • reply_order_status

My problem is that I have to set the slot value in the story, if not, the rasa core will not use the memory-prediction, and to use the Keras to give a result(sometimes not correct). The number of order is different to a different user. How can I write the general story here? Thanks!
