The first slur in bar 31 serves a double purpose in A (→GE): it is part of the triplet marking and at the same time it defines its articulation. When correcting FE (→EE), Chopin included a longer fragment of the phrase under the slur, and therefore the initial triplet slur lost its motivic and articulative meaning. In this situation we omit that slur, considering its preservation to be an inaccuracy of correction (cf. General Editorial Principles, point 16).
