Hi, I checked your preset. It modifies the message too much. Can you only modify the system prompt without changing the rest of the user messages and the assistant message to fix the last message of the assistant? I added what you proposed in the system prompt and still have the same hallucination issue.

Changing anything other than the system prompt is like cheating fix.
