 in GE is most probably a mistake, perhaps consisting in copying this marking from bar 149, which in FE is at the beginning of the last line on a page, as is bar 145 in GE.

In FE (→GE) we can see here "zf", which we change to the correct . The issue of the Chopinesque notation of forzato and its variants in other sources is discussed in detail in the note in bar 1. In EE it was revised differently, arbitrarily, providing a  indication.

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.
