There is no  in bar 14 before the last note in the R.H. in FC, FE and EE1. Similarly in bar 16, where the sign is absent in FC and EE1, whereas it is present in FE (probably added still in the base text to this edition). These patent oversights of Chopin were completed in GE and EE2 (→EE3).

The version of FE1 is certainly erroneous. The omitted g1 note was added in FE2. At the same time, mistakes were not prevented – a totally unjustified  was added before the added note, dedicated probably for the bottom note, b – cf. the previous note.
