I experience the same, upon calibration the test screen does not work properly but eye gaze ray appears to work properly in scene. I suspect the bug is in the calibration test scene and not the calibration itself. Perhaps test with gaze ray and interactive objects in your scene to be sure.
The calibration result is strange.
