I have a question about the TwoStageFallbackPolicy: I used the Rasa demo as a template for the defaultAskAffirmation action: rasa-demo/actions.py at master · RasaHQ/rasa-demo · GitHub, and extracted present entities in the user message to tailor button titles and payloads.
When the NLU does not reach the treshold, the buttons are correctly filled, but upon selecting a button, my fallback bot utterance gets triggered. I assume this happens in the ‘action_revert_fallback’, where UserUttered is filled with my button payload, but seems to get reverted afterwards? How to prevent this behaviour, do I need to override action_revert_fallback?
