b. 22

composition: Op. 28 No. 13, Prelude in F♯ major

G-g in A (→FCGE) & FE2 (→EE)

A-a in FE1

b. 31-32

composition: Op. 28 No. 13, Prelude in F♯ major

d2 tied in A (→FCGE) & EE2

d2 repeated in FE (→EE1)

..

The absence of a tie to d2 is almost certainly a mistake by the engraver of FE (→EE1). The tie was added in EE2, presumably upon a comparison with GE1.

b. 33-35

composition: Op. 28 No. 13, Prelude in F♯ major

Pedalling above R.H. in A & FE2

Pedalling with no  in b. 35 in FC

Pedalling in GE

No markings in FE1

Pedalling below L.H. in EE

..

The pedalling in these bars, written by Chopin above the R.H. part (cf. Concerto in F minor op. 21, mvt. 1, b. 96), was omitted by the engraver of FE1 who perhaps was not sure where to place the markings. They were added in FE2 in accordance with the notation of A, however, EE moved them under the L.H. part.
The  sign in b. 35, overlooked in FC, was added in GE at the end of the first half of the bar.
