Categorical Slots - why is the slot being populated with a value not in the list from domain.yml?

Rasa Open Source

The behavior seems to be much-much better after I added the entities step to my “other” story, thanks!

  - story: Ask Attraction Open - Not Recognized with entity and other slot
    steps:
      - entities:
          - AttractionName: Lorem Ipsum
        intent: ask_attraction_open
      - slot_was_set:
          - AttractionName: __other__
      - action: utter_ask_attraction_open_not_recognized
