When interpreted literally, the chord on the 3rd beat of the bar in A (→FC) consists of the following notes: F1-F-b-d1-f1, which, in turn, results in a G major chord (F major), which could be a part of this harmonic sequence. However, Chopin would generally avoid such an unnatural orthography; therefore, he most probably overlooked here the naturals lowering all f notes to f. They were added both in FE (→EE) and GE, and the composer did not question the printed naturals in any of the three teaching copies containing annotations coming from him.

..

In A (→FC,FE→EE1) and CGS there is no  lowering b to b. Chopin's mistake, obvious in this context, was corrected in GE and EE2. The fact that Chopin was convinced of the presence of b in the preceding part of the bar is evidenced by the naturals written in A before B1 and b on the 4th beat of the bar.

composition: Op. 28 No. 9, Prelude in E major

..

In A (→FE) and CGS, there are no accidentals in the L.H. part in the entire bar. Chopin's patent inaccuracy was corrected by Fontana in FC (→GE), who added naturals lowering G1-G to G1-G and D1-D to D1-D. An identical addition was introduced in EE. The accidentals were also added in FED.
