In FE (→GE1,EE) the slur ends on the last note in bar 31. In similar bars 5-7, the slur is led to the 1st note of bar 7, which ends the phrase. A possible reason of the slur's shortening in the editions is the inaccuracy of notation of A, in which Chopin ended the slur just before the bar line between bars 31 and 32.
