I just added some of the Rasa fallback options such as the FallbackClassifier and the RulePolicy core_fallback… ones and a rule for fallback and an action replacing the default fallback action. And now it all stopped working. When I look at the debug information my intent gets 0.98 .but it still do not think it is the correct intent so it fallbacks. But at the same time it calls the action of the intent. But the action_fallback then clears the slots (from UserUtteranceReverted) that the actual intent set. And then it is really messed up. And even if I delete all of this, it still gives me fallbacks that I do not want. Please help!!!

Did that and it still fallbacks

@MatsG how many training examples for your nlu intents ?

So I get TWO messages returned. One from the correct action and one for the fallback action. I have a number of rules since I want the user to be able to change between the intents a lot. But there are some dependencies on previous intents/actions setting up slots to be used later. What can cause this behavior? I tried changing my stories. Have tried adding lots of stories with alternatives and tried … You can see my nlu file there
