In JC there is no 
lowering a3 into a3, which is a patent error; in the copy there is also no relevant sign before a2. PE is also missing a flat before the latter, which can correspond to the notation of [A], as Chopin often extended the validity of cautionary accidentals onto entire passages or scales of this kind.
The same applies to bar 46, marked in the sources as a repetition of bar 19.
