The flat restoring e1 is only in AsI, which means that neither Chopin nor the revisers of the editions noticed this obvious mistake.

In the majority of the sources there is no accidental to the 8th semiquaver in b. 104 and 108. Admittedly, any doubt is dispelled by the following f3 semiquaver, but the absence of the  restoring f3 after f2 at the beginning of the bar must be considered a mistake due to the rule (frequently applied in the sources of the Variations) according to which accidentals are valid at a given pitch regardless of the use of an octave sign – cf., e.g. b. 35, 39 or 335. Therefore, we add them both in the main text and in the content transcriptions of the sources (versions "edited text"). Naturals were also added in GE3.

b. 119

composition: Op. 2, Variations, complete

..

There is only one  before the chord at the beginning of the 2nd half of the bar in AsI and A, a  to the bottom note (the bsemiquaver). What is more, in A the accidental was written inaccurately, above the semiquaver, as a result of which GE1 assigned it to d3. Both missing naturals were added in the stage of proofreading of that edition. Chopin's patent oversight was corrected right away in GE1, hence all editions contain the right text (the fact that the  to d3 was printed first is evidenced by the arrangement of the naturals and by the slight difference in size between the  of d3 and the two remaining ones).

In AsI the accidentals restoring c1 and b at the end of b. 137 are missing; the  raising e1 to e1 in b. 138 is absent too. A similar situation occurs in the L.H. part, which is marked in an abridged manner as doubling in unison the R.H. part. In A and the editions the notation is correct.
