FE
compare
FE has dotted crotchets instead of minims. It is hard to imagine that one could have committed such a striking mistake, therefore, it seems to be more plausible that the engraver changed Chopin's notation on purpose, most probably considering the chords in the L.H. and the R.H. as two beats filling this bar.
