Your clone is giving wrong answers
Diagnosing by the kind of wrong.
It states an old price or an old offer
Stale material. Find the source that mentions it and delete or replace it. Then put the current figure in the Who you are field, where it is one line to maintain.
It contradicts itself between conversations
Two sources disagree, and which one wins is not predictable. Delete the outdated one rather than adding a third that corrects it.
It invents things you never said
Check that Only answer from my material is on. With it off, your clone fills gaps from general knowledge.
It is right but not how you would say it
Not a knowledge problem. Rewrite the answer in Test Arena and strengthen your tone of voice field.
