She isn't even called that in the English version just as Elena is not Myrna or Rufus Rufhaus. The Program has her correct Name and that is not Aeris. As well as Beerus from DBZ is not Bills or Sephiroth is not Bizarro or Safer or other translations that completely tell something wrong. Just because I say something and use a wrong word for it I do not actually say the wrong thing someone understands as the intention is still the original one. Just as a mistranslation says, Sephiroth was created 5 Years before Final Fantasy VII which is not true at all.Just as Yuna says to Tidus she loves him which is despite no misranslation not true as she only thanks him.
