FE feature an erroneous f
on the 2nd quaver, which can be considered a result of an oversight of a 
before this note or a Terzverschreibung error. Oversights of marks in such situations are very frequent in Chopin's, and not only, works, hence we adopt the version with f
as the text of FE (in the version "editors"). FE was interpreted in the same way in EE; a was added also in FEH. This prescriptive, "routine" addition, however, does not take into consideration a broader context – the accompaniment structure in bars 71-76 clearly indicates a Terzverschreibung error, hence a d note. Such an interpretation was adopted in GE; it is also confirmed by the correction in FES. According to us, the entry in FEH does not have to mean that Chopin paid attention to this place – the mistake is so blatant that the pupil could have introduced the correction by herself still before presenting this movement to the composer.
