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.

In the 2nd half of the bar A does not include an accidental to the 2nd R.H. quaver, which results in a. In the next two bars, in which the same figure is repeated an octave or two octaves higher, the respective notes are provided with naturals. Therefore, there is no doubt that in the discussed bar Chopin overlooked the . It was added in GE (→FE,EE,IE).
In the main text we do not include the  to the last L.H. quaver, f, added in GE (→FE,EE,IE) – in this layout it is superfluous.
