Wheels and Wheel colliders going in sky

I am trying to make some cars move using promoteo vehicle physics. Its working fine with other cars but the wheels and wheels colliders start going towards sky in upwards direction as soon as I start playing. Here is the video: https://drive.google.com/file/d/1Dy0j3AFpbkBJdA2Jg60eKK_5YgFKncXU/view?usp=sharing . Please help :pray: :pray:. I am a begginner.

I have used this asset before but have not had this problem.
I watched the video and it seems the wheel is colliding with another object continuously or something it applying a force or changing its position values
