b. 22

composition: Op. 45, Prelude in C♯ minor

g1-a1 in FE (→EE)

a1-b1 in GE & FEJ

..

The fact that FE (→EE) have got a mistaken version here is testififed by the version of GE and a hand-written correction in FEJ.

b. 22-23

composition: Op. 45, Prelude in C♯ minor

..

Lack of sustained in FE is doubtless a mistake, as we can conclude from the presence of the tie in GE (and EE) and from analogous bars, e.g. 8-9 and 12-13.

b. 26-27

composition: Op. 45, Prelude in C♯ minor

..

In FE1 there is no  lowering gto g2, neither before the penultimate quaver in bar 26, nor at the beginning of bar 27. These patent inaccuracies were corrected both in FE2 and in EE. Moreover, in FE, both in the last octave in bar 26 and in the chord at the beginning of bar 27, all c notes have sharps. In EE the sharps are left only in bar 26. GE has a correct text in accordance with the modern notation rules.

b. 27

composition: Op. 45, Prelude in C♯ minor

..

In FE1 there is no  lowering f1 to f1, which was added in FE2 and EE. A suitable accidental is also in GE. Moreover, in EE there is a  in front of d2, the last quaver of the bar.

b. 28-37

composition: Op. 45, Prelude in C♯ minor

..

Three last quavers in bars 28, 31 and 37 do not have accidentals in FE1. That Chopin’s notation inaccuracy was corrected in FE2 (apart from  of e in bar 28). The notation of GE and EE is completely correct.
