Why MPU-6050 Accelerometer reading a half of 1G?

[browol]

Hi, Question about Accelerometer Scale Sensitivity Factor

wrong values reading

I have read accel values 8192 at +/- 2g

but its should read 1g  of 16384 at sensitivity of 2g

From Datasheet https://www.invensense.com/wp-content/uploads/2015/02/MPU-6000-Register-Map1.pdf   P.29

AFS_SEL | Full Scale Range | LSB Sensitivity
--------+------------------+----------------
0    | +/- 2g    | 16384 LSB/g
1    | +/- 4g    | 8192 LSB/g
2    | +/- 8g    | 4096 LSB/g
3    | +/- 16g   | 2048 LSB/g

 

Is somethings wrong?

 

Thanks in advance.
