..

In A (→GE1) the 5th and 6th quavers (f1 and g1) have superfluous accidentals (in FE only g1), whereas the unnecessary natural in EE appears also before the 4th quaver c2. Those are the remains of original notation of the 1st crotchet in that bar.

On the 8th quaver in A, FE and EE1 there is no natural reinstating f1. Chopin corrected his mistake in FEJ and FES. The sign was also added in GE and EE2.

In A Chopin changed the notation of the 1st and 3rd notes from c2 and g2 to b1 and f1. The unnecessary accidentals in the 2nd triplet in the bar are remains of the original notation.

On the 4th crotchet of the bar in FE there is no flat reinstating b1, which is an obvious error.

In EE all the triplet's stems were doubled, which is an obvious error. The remaining sources unanimously confirm the version with one crotchet stem.
