In A the staccato mark under the 1st quaver is in the form of a wedge, and this is how we give it in the main text. In FC (→GE) Fontana must have assumed that the top part of the mark was an unintentional trace of a pen, which cannot be ruled out completely, although such defects in the notation of dots are very rare in Chopin's autographs – cf., e.g. dots in the Prelude in G
Minor No. 12: out of 79 staccato marks, 77 are dots (only R.H. marks in b. 65 and 73 should rather be regarded as wedges), among which only two in b. 9 are not round or punctual.
