Issues : Omissions to cancel alteration

b. 9-13

composition: Op. 10 No 2, Etude in A minor

..

The naturals returning a1d2 and f2 in bars 9 and 13 are inaccurately written in some of the sources. In CLI they are totally absent, although in bar 13 the sign returning d2 is before the last semiquaver in the lower voice. In FEcor Chopin added them only in bar 9, yet, eventually, he also added the  returning f2 in bar 13 in FE (→EE2). In GE1 only the sign returning din bar 13 is missing. The remaining sources have the correct notation.

composition: Op. 10 No 7, Etude in C major

..

In A there is no  returning a2 on the 10th semiquaver. This obvious oversight was corrected in FE (→GE,EE).

In GC (→GE1), FE and EE there are no naturals returning B-b. This patent oversight was corrected in GE2 (→GE3).

b. 12

composition: Op. 10 No 2, Etude in A minor

..

In CLI, FEcor and EE2 the  returning d1 on the 4th beat of the bar was omitted, which is a patent error. Same as in bar 4, in CLI there is a superfluous  before gbefore this triad.

e2 in A

e2 & e2 in FE (→GE,EE)

..

Lack of the  returning e2 on the 7th semiquaver and the  returning e2 two semiquavers later clearly suggests the use of the C minor chord in the middle of this bar. Chopin's proofreadings of FE (→GE,EE), however, ensure that, similarly as in bar 4, the composer's intention was the C major chord (in A analogous bar 37 is already written correctly).
