In FCI there is no 
lowering f
to f in b. 18; it is also absent in b. 19-22, in which the L.H. part is marked as a repetition of b. 18. Chopin's patent oversight is evidenced by the cautionary 
before f in b. 23. This situation affects the evaluation of the notation of b. 16-17 – it is also there that we are almost certainly dealing with an oversight of naturals (in the R.H.).
See also b. 22.
