It is unclear how the two slurs in A are to be understood: their range is practically identical. Therefore, it seems that Chopin either wrote one of them by mistake or wanted to replace one of them with another. This is how it was interpreted in GE, reproducing only the top slur. We give this version in the main text, since all following similar figures have only one slur, mostly the top one. The absence of the slur in FE must be a mistake, corrected in EE, probably on the basis of comparison with analogous bars.
