In A (→FE) there is no  lowering d2 to d2 in the 1st chord. A relevant accidental is also absent before the topmost note in the L.H. In GE and EE the flats were added, yet in EE3 only the one in the L.H. In the main text we remove the unnecessary  before d in the 2nd half of the bar, which appears in the sources.

A does not include the  before the topmost note of the chord on the 3rd beat of the bar. This patent oversight was completed in FE (→GE,EE). In turn, in all sources, except for GE3 (→GE4), there are unnecessary flats before c2 in this chord and before f2 on the 4th beat of the bar.

d in A (→FE→GE)

d in EE
..

In the main text we give d (with a cautionary ) after A. In FE there are two accidentals before this note,  and , one on another. It is an easier performed correction, however, it is unclear which of the signs was supposed to be removed and which should be considered as binding. GE includes a  and EE – .

..

The cautionary natural before f was added in a proofreading of FE (→GE,EE), most probably by Chopin.
A (→FE→EE,GE1→GE2) includes a repeated  before the 12th note in the L.H. The unnecessary in this context accidental was removed in GE3 (→GE4).
