FE overlooked the general part of the octave sign over the initial, highest fragment of figuration (in the majority of the sources, including FE, it embraces also half of bar 6). The only visible trace of the indication is the word loco, which was used to end the octave sign in the times of Chopin. This patent error was corrected in FED and FEJ.

In EE there is no  returning d4 at the beginning of the 2nd group of semiquavers. This rather obvious error remained unnoticed by the revisers of EE and was never corrected. According to us, it is possible that it was the copyist writing the base text to EE that committed the mistake, as in analogous bar 69, which was marked as repetition of bar 1 in the manuscripts, a respective  was probably added in EE in print.

GC (→GE1) features naturals before b3 and a3 in the 3rd group of semiquavers. These unnecessary signs are remnants of the erroneously repeated 2nd group of semiquavers in this place. The mistake was corrected, by changing only the elements influencing the correctness of the text – pitch of the notes,  to  before the 3rd note. In GE2 (→GE3) the naturals were already not included.
