VL53L1X issues with reading distance

[FlorianJaeggi]

I am currently using a VL53L1X Sensor to read a distance in the range of 40cm to 130cm. 
I initialized the Sensor to work in the short distance mode, so the range should not be a problem. 
I used the VL53L1X_calibration library to get the values for offset and xtalk. 
In the Datasheet i read that with the function VL53L1X_GetDistance() the distance should be returned in mm. 
The value i get returned from that function does change when i change the physically measured distance, but it is not the expected value. For example when i want to measure a distance of 1m i get a value of about 55500. 
Also the measurement change on the same height in a range of 1000. 

For the offset and xtalk calibration i set the physical distance to 1m and gave that as a parameter in the function as 1000(mm). 
I copied the values i got from the function to the function setoffset and setxtalk. 
To calibrate i used the following diagramm:

And my init in my software looks like this:

I dont really understand why my measurements are this far off, have i maybe missed something in the calibration or init? Or are there other possible faults i have made?

I have found the Solution, in the library VL53L1X API i used the function getdistance. 
I dont know exactly why, but the High and Low Byte were switched so it gave me a wrong reading. 
Everything is fixxed now.
