Seems like you might be right Marco! The results of the last cat.2 don't appear on CyclingNews stage result article or on the official Giro website, which is where I suspect the stage was scored from.
I'll double check and run an update as soon as todays stage has been scored.
There is a flaw in the official Giro Website. I leave you here the link where you can see this.
