Then I want to confirm your question. Do you want help to check the reason why you got uplifting value in your result, right?
From attaced screenshots I think the processing is not stable and reasonable but we need very detailed information to understand what you did. Do you have a detailed processing memo document then we can clearly understand and help you on that?
