b. 6

composition: Op. 28 No. 11, Prelude in B major

..

FE overlooked the  restoring e1 on the 5th R.H. quaver. The accidental was added in EE; it was also entered into FEJ, probably by Chopin.

Slur in A (→FCGE)

No slur in FE (→EE)

..

The absence of a slur is certainly an error by the engraver of FE.

b. 6

composition: Op. 28 No. 24, Prelude in D minor

..

At the end of the bar, one can see a crossed-out  marking in A. Crossings-out of those markings in similar situations are also present at the end of b. 20, 41 and 54.

b. 6-9

composition: Op. 28 No. 23, Prelude in F major

3 slurs in A (→FEEE)

2 slurs in FC (→GE)

..

The slurring of FC (→GE) proves the copyist's distraction, perhaps due to haste. The change between b. 6 and 7 could be explained by an inaccurate interpretation of the ending of the slur added in A (Chopin must have meant leading the slur to the last semiquaver in the bar and not combining it with the next one). The broken slur between b. 7 and 8 probably is an inaccurate interpretation of A (the fragment of the slur at the beginning of b. 8 is poorly visible in A) or a mistake (b. 8 ends the line in FC, just as b. 7, which begins similarly, ends the line in A). The slur at the end of b. 8, which ends the line, implying that it should be continued may have simply been carelessly written down.
