As was the case 8 bars earlier, in AsI there is no  raising e1 to e1. An analogous deficiency is in the L.H. part too, which is marked in an abridged manner as a doubled R.H. part (an octave lower). The notation of A and the editions is correct.

A respective accidental is in the 2nd violins in AsI and the orchestral parts. The mistake was corrected only intermediately – in a later version of this insert, added in the stage of proofreading FE1, there is an a1 provided with a .
