As was the case with analogous b. 31 and 57, the slur of GE, although formally correct, is most probably inaccurate and marks a grace note and an arpeggio (written down as a vertical slur). The missing slur (arpeggio) in FE (→EE) is most probably an oversight by the copyist in [FC] or by the engraver.
