FE1 includes an erroneous  before the top note of the last third. All the remaining sources feature the correct .

 raising d2 to d2 in FE3 (→FE4)

..

The natural raising d2 to d2, added – most probably by Chopin – in the proofreading of FE3 (→FE4) is most likely a correction of a mistake and not a new version of this detail. The bottom notes of the dyads (and in the chords also the middle ones), unless they are an octave doubling of the top voice, always belong to the components of a current chord in the entire section comprising bars 17-36.

All sources except for EE1 added a reminder  next to the last ein L.H. We omit this accidental in the main text.

b. 24

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

On the 2nd quaver of the bar FE1 has an erroneous g1-b1 instead of e1-g1, whereas on the 6th quaver g1-a1 instead of e1-f1. The double Terzverschreibung error was corrected in the subsequent FE. The correct text is also included in the remaining sources.

F in GC (→GE) & FE2 (→EE,FE3FE4)

B in FE1

..

B on the 4th quaver is almost certainly a mistake of FE1.
