VKB-SIM

I did not touch anything but the red lines are shaking. And then when I pull or push the x-axie and the y-axie, sometimes that empty space is created. Inside the game, x-axie and y-axie shake just like the lines of a joytester picture. This happened right away when I first bought it. I want to know ...

Is there a problem here?

firmware version is 1.85b
Gladiator mk2 issues x-axis and y axis...

The red line and the black line continue to shake.
If I move X-AXIS and Y-AXIS, there will be empty spaces in the line.
