In A the d1 notehead in the 2nd L.H. quaver does not align with g and f1 (vertically) and is not adjacent to this quaver's stem. Perhaps this is why it is absent in GE (→FE,EE,IE). The regular nature of this chordal sequence makes a very strong case for the presence of this note (cf. also bars 71-72).
