Maybe you haven't set up your aircraft's profile correctly for fuel burn? See page 26 of the user manual.
You have to set fuel burn for the following phases of flight:
Taxi, take off, holding, landing and contingency.
I had to experiment with my settings so the SD calculation of total fuel burn was close to what I use, on average, for all phases of a flight.
For me I use around 16.5 litres of fuel for one hour of flight, including taxi, engine run, take off etc. etc.
Also don't forget that SD adds on a percentage for contingency which affects the "litres per hour" fuel figure.
