In A entire b. 16 and the 1st R.H. quaver in b. 17 were first written in an earlier version: . Chopin then crossed them out entirely and entered the final text, although not without hesitation (mistakes?) – in the later version the 6th R.H. quaver was initially written down in the original version (d2-d3), while at the beginning of b. 17 there was most probably an f1-a1-d2-fchord.
See also the note in b. 17.

b. 17

In A the second part of the passage was crossed out and rewritten. The reason could have been, e.g. Chopin's mistake, who wrote the passage as if there were no octave sign over the first part thereof, hence without f2-e2-d2-a1. However, it seems more likely that it is a trace of the initial version of the passage, which started an octave lower: . The latter is supported by the fact that the octave sign seems as if it were added to the finished text, e.g. it overlaps with the accent. Broadening the span of the passage would also harmonize with the similar corrections performed in the previous fragment – see b. 16-17.

The missing  mark must be Fontana's mistake.

The crossing-out visible in A proves that Chopin initially entered that mark before the f3-f4 octave.
