FE and EE1 have an as the 4th quaver of the bottom voice in the L.H. This patent error almost certainly happened to Chopin in [A], as the note on this pitch was initially written also in GC. Besides GC (→GE) the correct text was also introduced in EE2 (→EE3).

In GC, FE and EE1, there are no naturals before the 1st semiquaver and 2nd quaver in the R.H. (g1 and d2). Both patent inaccuracies were corrected in GE, whereas in EE2 (→EE3) and FES, only the first of the signs was added, the  lowering g1 to g1.
