Below you can find the original version of the accompaniment in the 2nd half of the bar: 
. This version is present in A, but the 2nd, 3rd, 5th and 6th quavers are deleted; below, there are notes of the final version, placed a third lower. However, the traces of corrections present in FE prove that the deleted version was initially printed also in FE and only then changed in print to the final text. It is difficult to say how it occurred – the engraver could have misunderstood the correction in A (it is unlikely, since it seems clear) or Chopin could have had also A in front of him while proofreading FE1 and, by mistake, marked the correction in the manuscript first. Cf. a similar situation in b. 159-160.
