The last note of the 1st half of the bar (b) was corrected in A, while the effect of these changes turned out to be unclear for the engraver of FE who found there c1. The mistake was corrected both in GE and EE.

 in A

No markings in FE (→GE,EE)

..

According to us, omission of the  marks in the editions is of accidental nature. Cf. bar 16, as well as the Etudes in Gmajor, No. 5, bar 32F minor, No. 9, bar 4C minor, No. 12, bar 27.

Tie in A

No tie in FE (→GE,EE)

..

Oversight of the tie by the engraver of FE (→GE,EE) seems to be more plausible here than Chopin's possible proofreading in FE. Similarly in bars 52-53.

Tie in A, GE & EE

No tie in FE

..

Same as in bars 50-51, we consider the omission of the tie by the engraver of FE to be more plausible than Chopin's possible proofreading of FE. However, in this place a tie was added both in GE and EE.
