In JC there is no octave sign in those bars. It is probably an error, which is revealed by the analogy with the shape of figurations in bars 70-71, as well as by an unequivocal oversight of the octave sign in bar 71.

In JC there is no  returning e on the 2nd crotchet in bar 86; in turn, there are two other unjustified signs – before on the 3rd crotchet and a  before e at the beginning of bar 87. According to us, the latter were mistakenly written two crotchets too far, hence we omit them.

..

In JC the lower voice was not written down (neither the quaver nor the ties), which is a patent error. We do not complete this notation, as it is impossible to determine what was exactly omitted by the copyist.
