That is interesting because she does see it as a closed issue and most likely wouldn't return to it. However, I do not think she is trying to make the results fit her. She probably just read this short/horoscopic descriptions and said that's that because it does fit her, it's just I see those same traits (hardworking and likes to plan and other stuff) in her but they manifest in a way that's not ISFJ-like.
And while ISFJ and ESFJ have traits in common, if she WAS an ISFJ you would definitely see a difference, because the ISFJ's focus on life is internalized and this can make them seem a little strange to their family members and others who know them well.
