In FE we can see here "zf", which we change to the correct . We discuss in detail the issue of the Chopinesque notation of forzando and its variants in the sources in the note in bar 1. The symbols introduced by GE and EE were arbitrary attempts at finding the correct substitute for the erroneous FE notation.
In FE it is unclear whether the indication is supposed to concern the left or the right hand. We assume that it concerns the left hand, as the mark is still over the initial octave, which suits the music better if we take into account the fact that Chopin would use  as an accent. The marks in GE and EE rather refer to the R.H.

Starting from a3, the sources are devoid of flats. In Chopin's time, there were no strict rules concerning the scope of accidentals under an octave sign (or they were not strictly observed), hence accidentals were often omitted in similar situations. Wherever the text is obvious, as, e.g. in this case, we add respective accidentals in content transcriptions and in the main text.

The missing  in the sources could be an oversight, although such isolated  marks can often be found in Chopin's pieces, especially at the end, but not exclusively. In the main text we suggest adding [] to keep the performer from an earlier pedal release, which could be contrary to Chopin's intention, considering the crescendo.

The natural raising b3 to b3, omitted in FE (→GE) – cf. the end of bar 212 – was added in EE. The patent mistake (by the engraver or by Chopin) is proven by the cautionary  to b3 at the beginning of the next bar.
