Strange Behaviour of Springs?

Hello there! I have been trying to add A-Chassis to a GTK Boxer model i just got.

There are some issues with it though: The springs break when i add more than 4 Wheels For some reason only 4 of the springs in the car work

I dont have any clue why this is happening! Is it a physics bug? Or something else with A-Chassis?

Does anyone have the same kind of problem or even a solution for it? Or maybe a veheicle with more than 4 wheels witch works.

Here is a video showing the ignorance of 4 springs with a veheicle containing 8 Wheels. https://streamable.com/8nqrx2
