No slur in JC

Slur in EF & PE

e3 in JC

In EF first three groups of demisemiquavers are written with an octave sign. In JC the notes are written in the same way, yet the octave sign was omitted, which is a patent error. In this graphic layout the f2 note at the beginning of the 4th group requires the  sign to be repeated, which actually is featured both in JC and EF
