The absence of a must be Chopin's oversight (this bar is written in A at the end of the line, which promotes inaccuracies). In the main text we suggest adding the mark analogously to the 1st half of the bar, since the authenticity of the mark added in FC (→GE) and FE (→EE) at the end of the bar is questionable.
