Both source versions of slurring are most probably authentic. In the main text, we give separated slurs of A, yet the slur of GE (→FE→EE), being probably a result of the Chopin proofreading and compatible with the slur of analogous bar 20, can be considered an equal variant. We give priority to the version of A, since when proofreading GE1, Chopin would change the misinterpreted slurs in the edition and not the ones he wrote in A.
It is not clear, however, whether the absence of staccato dots was due to an oversight or a correction. In the editors' opinion, the dots were probably overlooked by the engraver, which together with the wrong slurs lead Chopin to write one slur during the proofreading. The GE2 version, although arbitrary, integrates the authentic elements of the notation into a consistent whole, which Chopin would supposedly deem acceptable.
