This is due to a miscommunication between CartGrid3D and Carpet.   
CartGrid3D "wants" to calculate the information only on the coarsest  
grid, and there is no clean way to specify "call me only on the  
coarsest grid".  There was a reasonably elegant work-around in  
CartGrid3D, which unfortunately didn't work with a different driver.   
I have updated the test again.
