The missing 
mark in FC (→GE) is almost certainly a result of an oversight of the copyist. The omission of the mark in CGS is most probably of a similar nature. The addition of the 
mark in b. 26 must be a revision of EE, quite frequent in Chopinesque first editions – cf., e.g. the Prelude in C Major, No. 1.
