Issues : Accidentals in different octaves

b. 10

composition: Op. 25 No 8, Etude in D♭ major

..

In A (→GE1) and FE there is no  raising d to d. This characteristic inaccuracy was corrected in EE and GE2 (→GE3). The latter also added a  before a2 on the 4th quaver, poorly justified  before a on the 8th quaver and a completely incomprehensible  before c2 on the 10th quaver.

We also add a  before d2 on the 8th quaver of the bar.
