The seventh E1-D, written in two-part notation, is definitely an error of FE1 probably resulting from carelessly done proofing. We give the octave D1-D as the intended version of that edition, which results in a version analogous to bar 243. It is not entirely unlikely that the correction was only meant to be done for the D1 note alone, just like in the remaining sources. In FE2, E1 was changed to D1.
