Issues : Uncertain notes on ledger lines

b. 41

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

Third c1-e1 in A, FE (→EE) & GE2

Only e1 in GE1

..

The engraver of GE did not notice the c1 notes on the 3rd and 5th quavers in A and he placed the  written before the 1st of them before e1. Chopin corrected this mistake in FE (→EE), however, the unnecessary  remained in all editions except for GE2.
