ISL29501 EVkit incorrect ranging

Hi - 

I am considering the ISL29501 sensor for an application.  I got the EV kit to be able more rapidly put together a prototype to test the ranging functionality, but I am unable to get even close to the readings I am supposed to.

I followed the video on the product page and then noticed that in the video, the device is calibrated to 30cm, but the measured distance displayed just below Reference distance is 259cm? I also see the calibration offset.  Does this then mean that values measured thereafter will be correct?

I this normal behavior?
