There are no accidentals to the chords in the middle of bar 185 and 187 in A (→GE), which, when interpreted literally, results in E
chords in both places, with g1 and g2, interfering with the E minor chords from the beginning of the bar, held with pedal. The overlooked flats were added – probably at Chopin's request – in bar 187 in FE1 (with a mistake – a 
to e1 instead of to g1) and in bar 185 in FE2 (→EE), but not in GE.
In the main text we omit the to the g2 quaver at the end of bar 187, unnecessary in the corrected version.
