Utter_action_feedback is selected as next action in rasa and rasa x even though intents and responses are written in stories

I am trying to develop an Faq chatbot on covid when i gave some intents and responses my bot identifying the intents correctly but it selects the next possible action as “utter_fallback” with confidence 0.30 and rewind both in rasa x and rasa. For the same given input it provides correct response then later if i ask the same input after a set of other qns it gives me utter fallback. Out of all for every min of one intent’s response will be choosing feedback action it won’t be same intent every time.
