Issues : Omissions to cancel alteration

b. 28

composition: Op. 25 No 10, Etude in B minor

..

In GC, FE and EE the only accidental before the last chord in the R.H. is the cautionary  before e1. According to us, the sign is not superfluous here, contrary to the  returning f1, which was added only in GE.

FE has an aas the 3rd crotchet of the middle voice in the R.H. It is almost certainly the so-called Terzverschreibung error.
In GC (→GE1) the correct note is an f1. This patent error was corrected in GE2 (→GE3), EE also includes the correct version.

Lack of the middle note on the 3rd beat of the bar is almost certainly a mistake of GC (→GE1).
In FE the note is present, yet there is no  returning F. EE and GE2 (→GE3) have the correct text.
