x15 R2, possible solution of reversed magnetic lid action issue

Today the magnetic sensor acts reversed, the screen is only on when I put my magnetic piece near the sensor area. After trying a lot, I figured out that the sensor may stick on one side. I put my magnetic piece on the opposite of that field, or maybe the edge of the computer, which is about the bottom right of the panel where the keyboard and touch bar are placed. And then magically the sensor reversed to act normal! You can give it a try if you meet the same issue.

Background: I've got an Apple watch, and I changed to a magnetic band recently, when I wear it on my right wrist. When it is close to the field right to the touch bar, the screen went down and acts as the lid closing. So I usually tried to avoid this situation.
