In A there are no accidentals before the upper minim in the L.H. at the beginning of the bar and before the penultimate semiquaver in the R.H. First of these undeniable oversights was corrected already in FE (→GE,EE), the second – only in GE.

In A the flat before the 5th semiquaver (e4) is arranged clearly too low, at the level of b3.

The  before the 5th semiquaver in A illustrates Chopin's idiosyncrasy, ocurring sometimes in his autographs, to write accidentals on a visibly different level than the notes they pertain to.
