None of the sources features the 
lowering e2 to e
2 on the 8th semiquaver of the bar. In such situations, when an accidental has already appeared at the same pitch yet under an octave sign, both Chopin and his publishers would often consider it to be valid. The inaccuracy, certainly repeated after [A], does not result in any textual doubts and is indeed hardly noticeable.
