..

In the majority of sources there is no  raising f3 to f sharp3. The sharp was added only in GE2

For writing that note Chopin used 4 ledger lines (one too many). He corrected his mistake by deleting the lowest ledger line. Interestingly, it seems that the engraver of GE did not notice the correction, as that edition has got visible traces of moving the note head down by a third.

d flat in A (→GE2) and FE (→EE)

in GE1

..

The note in GE1 is certainly erroneous: this is evidenced by the proofing - probably Chopin's - of FE, in which the d flat written in A was reinstated. The error was also corrected in GE2.
