Yes you're totally right! I misunderstood what you meant, let me write six more paragraphs based on a similar misunderstanding rather than just trying to get clarification from you
Doesn't matter if you tell it "that's not correct and neither is ____ so don't try that instead," it likes those two answers and it's going to keep using them.
The only reliable way to recover is to edit your previous question to include the clarification, and let it regenerate the answer.
