In A (→FE) there is no accidental before the 4th semiquaver. There is no reason to doubt that it is a typical of Chopin inaccuracy, resulting from the rules of validity of the accidentals, which in fact were not fully established in Chopin's notation. It is confirmed by the 
written in this place in FED. In spite of this, in GE1 (→GE2) there is a 
before this note, which is certainly a mistake.
