In A, there are no naturals to the b2 and b3 demisemiquavers. The latter was already corrected in GE (→FE,EE). In the case of b2, the missing  does not have to be considered a mistake, since the rules of validity of accidentals are not strictly determined in this context – b2 sounds higher than the b1 note at the beginning of the bar (an accidental is required) but it is written down at the same pitch (an accidental is not required). Interestingly, both naturals are in AsI.
