The slur of A undoubtedly begins from the 2nd quaver of the bar, hence the fact that it starts earlier in GE1 (→FE) is most probably a mistake. On the other hand, it is uncertain which note the slur of A is supposed to reach. A comparison with two analogous situations (bars 33 and 82) as well as separation of bass notes through articulation performed by Chopin in the entire movement tip the scales in favour of the slur ending together with the last chord in the bar. The interpretation adopted in the main text is present also in GE2. In GE1 the slur in bar 14 ends in a similar manner, yet in bar 15 one can see traces of deletion of the slur reaching the 1st quaver. It explains leading the slur from bars 14 until the beginning of bar 15 in FE.
