I have a lot of examples. I just tried it out. I asked Who killed JR? It correctly replied about JR in Dallas.

But then I said No, I'm talking about JR in babylon 5

  The response was 

I apologize for the confusion. "JR" in Babylon 5 refers to the character John J. Sheridan, who was the captain of the titular space station during the later seasons of the show.

  Sheridan was never refereed as JR in Babylon 5. There was no JR in Babylon 5. But because I asked, ChatGPT happily made up things.
