GE: the tie sustaining f2 from bar 9 is not completed.

FE (→EE): the slur begins earlier.

..

The slurs and ties of A, unambiguous in their meaning and extent, became somewhat distorted in the editions. In GE, due to the fact that bar 10 marked the beginning of a new line of text, the tie sustaining f2 had to be divided into two parts; although the part from bar 10 was accidentally omitted, the meaning of the curved lines printed in bars 9-10 remained unchanged and easy to guess. In FE (→EE), the earlier commenced slur seems to be a continuation of the tie from bar 9, which definitely suggests a change of meaning.

A slur in A

No slur in GE (→FEEE)

..

That slur in A is placed at a certain distance from the notes and obscured with the indication con forza. That is why the engraver of GE could overlook it or even consider it deleted.

b. 20

composition: Op. 27 No 2, Nocturne in D♭ major

..

In A Chopin forgot to repeat the tie sustaining a flat1 in the new system. This most probably caused an error in GE1, where that tie is missing. The error was corrected, probably by Chopin, in FE (→EE), it was also rectified in GE2.

L.H. articulation in A

FE (→EE1)

..

Correcting in FE the incomplete articulation markings for the left hand part taken over from GE1, Chopin changed his concept in that respect. The additions made in EE3 and GE2 are editors' corrections, although they make use of authentic markings.
