The stem sustaining the 10th quaver d2 in EE is certainly a mistake. The remaining three stems also seem to be erroneously placed one bar too early (cf. bars 29-30).

In A there are visible deletions of additional crotchet stems sustaining the sound of the 3rd and 6th quavers. It may stem from an attempt to try to make the sound concept of that fragment more precise or a correction of mistakes in designating similar bars.

In EE, starting from the 2nd triplet, there are no stems sustaining the sound of the last notes of particular triplets. Most probably, it is a mistake (cf. bar 28).

The slur b1-c2 in EE is certainly a mistakenly interpreted tie sustaining a1 (cf. the notation in A). Playing the a1 already at the beginning of the bar may result from a previous edition of this place.
