b. 72

composition: Op. 64 No 3, Waltz in A♭ major

Long accent in As (→A)

 in FE (→GE,EE)

..

The unequivocal long accent, introduced in A over the gminim, was placed in FE (→GE,EE) between the staves as a  hairpin. It is most probably an arbitrary decision of the engraver of FE.

b. 74

composition: Op. 64 No 3, Waltz in A♭ major

 below minim in A

 between staves in FE (→EE)

No sign in GE

..

In the editions the  sign, in A placed under the minim (it is generally a "very long" accent), was moved between the staves, which hinders its correct interpretation. GE overlooked the sign.

No slur in A

Slur above chords in FE (→EE,GE1opGE2opGE3op) & GE2Ab

Slur (tie) below chords in GE1Ab

..

The slur over the pair of chords could have been added by Chopin in the proofreading of FE. In GE1Ab it was moved under the chords, as a result of which it can be considered to be a tie of f1.
