Fit calculators are almost worthless. That reach value does not take into account the handlebar reach or brake hood reach. You do have legs on the shorter side, so your torso is a little long. Your stem might be a tad short, but it's not 30mm too short. Try moving the saddle back, no more than 5mm at a time. That increases the reach and may take some weight off your hands. If your saddle setback was adjusted by KOP, moving the saddle back 1-2cm won't hurt a thing.
