The d
note in GE is a result of overlapping the mistake of FE1 and revision of GE: the erroneous d note adopted from FE1 (without any accidental) was completed with a by the reviser of GE, who above all was concentrated on completing the missing accidentals, therefore, it was adjusted to the B7 chord. In a proofreading of FE2 Chopin changed d into B, restoring the version which – as shown by CLI – was the only intended one from the very beginning.
