b. 3-4

composition: Op. 63 No. 3, Mazurka in C# minor

 in FE (→EEW) & GE2 (→GE3)

No markings in GE1

..

The missing  marks in GE1 must be an oversight, corrected in GE2 (→GE3).

b. 5-7

composition: Op. 63 No. 3, Mazurka in C# minor

Lower register of accompaniment in FE1 (→GE)

Higher register of accompaniment in FE2 (→EEW)

..

The authenticity of the change of position of the accompanying chords and the bass register introduced in FE2 (→EE) is unquestionable. In a later version Chopin polished up the sequence of 3 voices contained in chords in the tenor and alto register and avoided a parallel shift of chords (G major→C minor) between bars 7 and 8.

b. 7

composition: Op. 63 No. 3, Mazurka in C# minor

b. 8-12

composition: Op. 63 No. 3, Mazurka in C# minor

 before 3rd beat of b. 8 & 12 in FE (→GE)

 after 3rd beat in EEW

..

The  marks having been placed in bars 8 and 12 after the 3rd crotchet is probably an inaccuracy by the engraver of EEW, who did not realise the change of chord on the 3rd beat of these bars.
