Hello

rasa 1.7.4

Short problem: Two stage fallback policy removes a slot set in a custom action when it detects low confidence intent.

Story looks like this:

```auto
* request_flight_info
  - action_prefill_flight_info_form
  - flight_info_form
  - form{"name": "flight_info_form"}
  - slot{"trip_type": "one way"} // categorical type
  - slot{"cabin_type": "economy"} // categorical type
  - form{"name": null}
  - utter_ask_form_confirmed // asks user to confirm slot values
* deny
  - utter_form_not_confirmed // tells the user he can make changes now
* change_origin_destination OR change_dates OR change_trip_type OR change_cabin_type OR change_contact_method OR change_passengers
  - action_change_form_slots // custom action to handle change intent and extract slots
  - utter_ask_form_confirmed
* affirm
  - utter_form_confirmed
  - action_search_flights

```

When user writes `change trip type to round trip`, intent `change_trip_type` is being detected with a low confidence. Even if it is detected with low confidence, custom action `action_change_form_slots` is being executed and slot is being filled with value `round trip`.

After that, two stage fallback gets triggered. User is being asked to confirm. When he confirms his intent, the slot is reset to it’s previous value and the flow continues.

Expected result: slot value should be `round trip` after user confirms intent

Current result: slot contains previous value after user confirms intent

Is this intended behavior or am I missing something?

Upon digging into this, I found maybe relevant logs that might point to issue

Anyone?

I forgot to mention that I was testing model from rasa shell. Is there any problem with that? Like shell buttons do not properly pass on entities, etc

Thanks

Hmm, well the custom action `action_change_form_slots` should be executed after confirming the intent with the user (by the two-stage FallBack policy). Can you please post the complete debug log of the server?

Now that I am looking into it more…:

1. The slot is being filled before two stage policy kicks in because slot autofilling is set to true in domains file and the slot name and entity name is the same. I guess this is intended behavior? But I am not sure that it is right for the slot to be filled before it asks user for affirmation
2. I put a log for `tracker.latest_message` inside run method `action_change_form_slots` and got this:

`{'text': '/change_trip_type', 'intent': {'name': 'change_trip_type', 'confidence': 1.0}, 'intent_ranking': [{'name': 'change_trip_type', 'confidence': 1.0}], 'entities': []}`

You can see that no entities are getting passed into this action after user confirms intent
