In the main text, we add naturals before the 1st and 3rd semiquavers of the 2nd half of the bar (a2 and e3). The absence of accidentals in such a configuration was not considered a mistake back in Chopin's times – the accidentals from the 1st half of the bar, although they refer to a1 and e2, were considered to be valid also in the case of a2 and e3 in the further part of the bar, encompassed with an octave sign.
