In A (→GE1FE) there are no accidentals in the last group of semiquavers. In EE the necessary  returning fon the last semiquaver was added, whereas in GE2 and EE3 two cautionary flats at the beginning of this group, before b2 and a(in the main text we include only the first one).

There is no accidental before the 7th quaver in the sources, which makes us interpret it as f1. The oversight of a  returning fis proved by fpresent in the viola part in Morch. In the corresponding bar of the exposition (bar 140), Chopin wrote in the 1st half of the bar c and e1 instead of d and f1, as a result of which a  next to f1 is not necessary there.

Same as in analogous bars 169-170, in A (→GE) there are no flats restoring a at the beginning of the 2nd half of each bar. The mistake was corrected in FE (→EE), probably at Chopin's request.
