Stories not working after fallback

Hi! So when we use fallback between a story, it was supposed to give the user a chance to again give their input and the fallback policy carries the conversation to the last working point and then the story should continue. But in my case, the story is not working as expected. I have attached the conversation with and without the use of fallback. What could be the reason for such a problem? Thanks

Hello RDS,

From the logs, it looks like after you provide the name then the action_default_fallback is called and returns event UserUtteranceReverted (pp4.png) and so the last slot (name) was reset to None (as seen also in the Current slots values of pp4.png). Could you share the story that this conversation follows and the rule you added for fallback?
