Understand the User Question

one week ago, my chatbot worked pretty good, the questions that didnt match an intent (NLU) got answered via fallback prompt. when i discovered, that there are settings for the intent, i wanted to TRY OUT the NLU + RAG version, but i didnt know, that i cannot go back from to my old version. right now, the chatbot isnt working really well for questions that are not part of an intent/utterance, pleaseee what is this ... can you leave the settings as they are??? its good that there are many new features and options, but isnt it possible to still keep the ones that were working??? its really frustrating.
