The naturals and flats added in FE (→GE,EE) change the chord on which the 1st half of the bar is based. Despite numerous missing accidentals in A, it seems to be highly unlikely that the proofreading was only a correction of an inaccurate notation. Apparently, at the stage of writing A, Chopin heard d from the beginning of bar 68, same as in respective bar 66 (bars 67-68 constitute a modified repetition of bars 65-66).
