In my HP Spectre x360 Laptop, I have tried to calibrate the pen using the below


I went half way and tried to cancel it. Now when i try to point the pen to my screen, it touches far up and right, even when i try to re-calibrate, I can not click on the points illustrated under the calibration. Please help me reset this thing and solve the issue.
