In CLI and EE2 the  returning d1 on the 4th beat of the bar was deleted, which is a patent error. In CLI there is a superfluous  before gin this chord, which shows that Chopin did not include in the notation the previous alterations in this bar at all. Similarly in bar 12.

Before the 7th semiquaver in A there is no  returning e1. However, there is a  before e1 on the 9th semiquaver, which would be unjustified, if the 7th and 8th semiquavers were meant to be e1. Therefore, an oversight of the  is beyond any doubt and it was confirmed by an accidental added in a proofreading of FE (→GE,EE). Analogous bar 37 is written correctly already in A. Cf. bar 12.
