In CLI there is no  returning don the 5th semiquaver in the upper voice. It must be a mistake.

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.

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.

b. 15

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

..

In CLI and FEcor there is no  returning d3 on the 3rd beat of the bar. Chopin corrected his oversight in one of later proofreadings of FE (→GE,EE).

b. 17

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

..

In CLI there are no naturals returning c2 and e2, nor the sharp raising g1 to g1. The second error – lack of the  before e2 – remained unnoticed also in FE (→GE1,EE2).
