In GC (→GE1), FE and EE there are no naturals raising c to c in bars 9 and 13 and c1 to c1 in bar 12. These are Chopin's obvious oversights, while the signs were added in FED (in bar 9) and FEJ and FES (all).
GE1 also omitted the  raising c1 to c1 in bar 10. GE2 (→GE3) features the correct text.

Accent in FED

Our variant suggestion
..

A reversed accent, sometimes used by Chopin (most often to highlight the note placed a second higher than the previous one), was added here in FED.
