FE has e1 as the lower note of the 1st semiquaver. This rather obvious from the pianistic point of view error was corrected in GE and EE.

d1 in FE (→GE,EE)

While proofreading FE (→GE,EE), Chopin changed the notation of the bottom note of the 5th and 6th semiquavers from e1 to d1. At the same time, he did not realise that after the change, a  returning d1 in the last pair of semiquavers should be added. The mistake was corrected in GE and EE4.

We add a cautionary  before c1. The accidental is already present in GE2 (→GE3→GE4) and EE4.
