b. 33

composition: Op. 21, Concerto in F minor, Mvt III

Separate slurs in A

Continuous slur in GE (→FEEE)

..

The division of the slur in A is probably the original version, left due to deletions and inability to write a continuous slur in a graceful way. However, such slur is in the L.H. and in GE (→FEEE), where Chopin's possible intention was interpreted correctly.

b. 34

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

..

The deletion in A allows one to see that originally Chopin wrote the sixth e2-c sharp3 as the 3rd quaver of the bar. The change was probably made after the whole bar had been written in - the proof of that is the   raising c2 to c sharp2 in the second half of the bar.

b. 34

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

..

All the sources have the unnecessary  before c sharp2, the lower note of the 3rd semiquaver. This is probably a remnant of the initial version of the 3rd quaver of that bar.

b. 36

composition: Op. 28 No. 5, Prelude in D major

Quavers in A & GE2 (→GE3)

No quavers in FC (→GE1) & FE (→EE)

..

Just like in b. 34-35, Chopin changed the pitch of the 2nd and 4th notes in A from g1-f1 to b1-a1. In this case, however, the crossing-out of both noteheads also includes the stems (pointing downwards) of the separated quaver voice, which resulted in it having been overlooked both in FC (→GE1) and FE (→EE). Assuming a mistake, GE2 (→GE3) separated both notes after the previous bars.

b. 38

composition: Op. 10 No 3, Etude in E major

..

Before the top note on the 7th semiquaver, the  returning f is only in GE4 (→GE5). It means the sound of f in AI and in the aforementioned GE, and in the remaining sources. However, there is no doubt that the missing  is Chopin's oversight, related to the correction on the 2nd semiquaver.
