The missing accent is most probably an oversight of the engraver of GE. In the main text, we suggest a long accent, since the shorter mark in FE is most probably related to its atypical placement between two top elements of the chord. Generally, it is impossible to reproduce such a notation, sometimes used by Chopin, e.g. in the Concerto in F minor, op. 21, the 2nd mov., bar 36, in print accurately.
