The slur beginning on the second beat of b. 28 in GE1 (→GE2→GE3) is most certainly inaccurate. It may have resulted from unclear marking of slurs in [FC1] which was the basis for these edtitions (e.g. when b. 27 was the last bar in the last but one line of text). The notation of slurs in A, however, leaves no doubts as for Chopin's intentions.
See annotation in bars 7-8.
