CLI has a sustained B as a bass note in these bars. This is the original version, moreover, it was almost certainly written with an error – same as in the adjacent bars, it was the B1-B octave that was supposed to be in this place (cf. e.g. bars 3 or 23-24).

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

..

In CLI there are no naturals returning a1d2 and f2. The accidentals were also absent in FEcor, in which Chopin, however, added all of them. Eventually, both FE (→GE,EE) and Ap have the correct notation.
