Collision groups are assigned but dont work

Hi i have 2 collision groups ( apart from Default ) that are Cars and Items

and the thing is that Cars are not supposed to collide with other Cars and items
While Items cant collide with Cars but between other Items

I have tried everything, the collision groups are assigned but they still collide.

A bomb can be shooted and should be in Items collision group

  1. Tried, creating groups from Studio and assiging manually

  1. Tried assigning via script

CloneBallBomb.CollisionGroup = "Items"

  1. Othey way via script

PhysicsService:SetPartCollisionGroup(CloneBallBomb, "Items")

How are you assigning the car’s collision group?

via studio, selecting the car, then I went to Collision group tab and assigned, all the parts of the model were assigned to the Cars group
