Knowledge Copilot - Ticket References Inaccurate

We are testing Knowledge Co-Pilot but we are finding that the ticket references it is using are inaccurate.  Usually only one ticket refers to the issue.  We have gone through the tickets to see if key words were triggering the response but we haven’t found any.  They are usually completely different and unrelated.  We also went through several examples and each time we found the same result.
