The slur added in GE1 (→FE→EE), clearly incompatible with the accompaniment's texture, is certainly erroneous, which contributed to it having been omitted by the reviser of GE2, who, above all, would check compliance with A. As far as A is concerned, one of two slurs combining the grace note with the f note seems to be superfluous, however, Chopin could have wanted to show that the grace note concerns both voices on the 3rd beat of the bar.
