In A (→GC) the slur breaks in the middle of the bar, which in A is caused by the fact of writing the 2nd half on a new page. This is how it was understood in FE and EE, in which the slur reaches the end of the bar. In the graphic layout of GC, in which this bar is not divided, the erroneous shortening of the slur is not that obvious and was arbitrarily recreated in GE.
