In b. 15, at the end of the line, Fontana ambiguously ended the slur in FC – the slur goes quite far beyond the last written-down chord, which could suggest a continuation, yet it does not even reach the end of the line, which suggests that the slur should end. As the ending of the slur was overlooked on a new line, in GE the slur was led only to the last written-down chord – the minim (with a quaver tremolo marking) at the beginning of the 2nd half of the bar.
The missing slur in CGS is an oversight of the copyist, who overlooked the majority of the L.H. slurs in the second half of the Prelude. The fact that she wrote the final fragment of that slur, encompassing b. 16, is an unquestionable evidence of distraction. See also b. 17-23.
