Ana being one of two stepsisters to Cinderella did leave timeline issues, which is why I was a supporter of the four stepsisters theory. Obviously, they decided not to go with that, but all that means most likely is Ana is part of a different Cinderella story (like how The Little Mermaid and Sleeping Beauty also repeat themselves).
