In A there are no cautionary flats before the 2nd chord in the L.H. The signs were probably added by the reviser of GE1 (→FEEE, →GE2), although it cannot be excluded that they were inspired by Chopin.

FE overlooked the  lowering g to g. The patent mistake was corrected in EE. The remaining sources also include the correct text.

In GE, the 2nd and 3rd triplets in bar 102 and the 1st and 2nd triplets in bar 103 were provided with an octave sign, so they are written an octave too high. The mistake stemmed from a change performed in the notation of this fragment – Chopin wrote it using an octave sign, whereas in GE1, planning on omitting 8 - - -, the notes were printed at the actual pitch, yet the octave sign was left by mistake. The error was corrected, probably by Chopin, in FE (→EE1), but it was unnoticed by the reviser of GE2. The erroneous octave sign was introduced also in EE2; EE3 restored the correct text.
