The version of A is, according to us, the only authentic text of this place. The sixth in GE (→FE→EE) is almost certainly a result of a misinterpretation of A – the engraver of GE1 considered the original ending of the stem of the g
quaver with a characteristic "hook" to be the B note. Deletion of this note in FES is probably a mistake too – the person who wrote this, perhaps Chopin himself, seeing two notes, out of which one was to be deleted and the other preserved, combined these two thoughts in one activity, by deleting the note that was supposed to stay (a similar mistake was committed in FES also in the Sonata in B minor, Op. 58, the 3rd mov. – in bar 28 a 
was added, confirming the erroneous text, instead of the mistakenly overlooked 
lowering a
1 to a1).
