In GC and EE1 (→EE2) there is no  returning c in the last chord in the L.H. The sign was added in GE and EE3, and probably also in the proofreading of FE.

In GC, FE and EE there are no accidentals before the 9th quaver, so it is not entirely clear whether it is to be read as e-e1-e2-e3 or e-e1-e2-e3. The comparison with the previous bar indicates a typical for Chopin oversight of naturals returning e and e2. GE1, however, added the  raising e3 to e3, which is certainly a mistake (yet it was repeated in EE3). The correctly written text is featured only in GE2 (→GE3).

In EE1 the top note of the part of the R.H. is mistakenly written as d3
