Range calculation not consistent, why is that?

When I go to the Software Version section of the Fleet menu I can see for example Model S 100D vehicles with range 1600, some other with 440 or 600km. That doesn't seem to be correct. Why is there such a deviation? It also looks like most of the cars in the US show at least 100km bigger range than those in Europe.

My Model S 90D shows 414km, which is spot on so I don't understand why it is incorrect for others.
