The accents over a3 in bar 230 and over a2 in bar 232 are undoubtedly long in A. Nevertheless, in GE (→FE,IE) they were reproduced as short accents, perhaps due to the significantly more dense text. The omission of one (in IE) or both (in EE) marks is due to the mistakes by the engravers of those editions.
