The cautionary natural next to g1 is included in A (→GE) and FE. EE is lacking the sign; it cannot be excluded that it was deleted due to its redundancy, which is indicated by the gap between the notes and signs of possible proofing.

A, FE and EE are lacking the natural next to the 10th quaver in the L.H. The sign was added in GE. The lack of the sign must be considered as an error, as ‒ despite the fact that is has only a cautionary character ‒ it appears in A in all analogous 5 bars (27-28 and 109-111).
