LIS3DH scale factor? 1g = 16600. Not 1mg/digit!

I'm testing a LIS3DH and set the FS bit to 00 (+/-2g measurement range).

I get about 16600 at 1g. The datasheet says 1mg/digit. 

Then I found in another application note (AN3182) that the sensor uses 12 bits left justified values. This could explain why I get this result.

Could anybody explain this?

What value should I get if I activate the self test? The datasheet says 276 for Ax. So this should be 276x16 = 4416?

I think the datasheet should need some rework to make things more clear.
