Issue with circle hitbox and physics group

[1nspect0r]

Hello

So,  got an issue driving me nuts. Trying to enable collision between balls, I wanted to make a body group but issue popped out, balls want to slide on the others, it's kinda random, sometimes it bounces as expected, sometimes not. 

It seems related to the shape because without the circle hitbox collisions are okay. But it was working without the group so...

  var balls = this.physics.add.group();

  balls.create(100, 250, 'blueBall').setDrag(0.975).setDamping(true).setBounce(1).setCollideWorldBounds(true).setCircle(200).setScale(.2).setInteractive();
  balls.create(200, 350, 'redBall').setDrag(0.975).setDamping(true).setBounce(1).setCollideWorldBounds(true).setCircle(200).setScale(.2).setInteractive();
  balls.create(100, 350, 'redBall').setDrag(0.975).setDamping(true).setBounce(1).setCollideWorldBounds(true).setCircle(200).setScale(.2).setInteractive();

  this.physics.add.collider(balls);

I had no issue at first without making the group, collision where perfect between two balls using this snippet : 

ball = this.physics.add.image(100, 250, 'blueBall');
ball.setDrag(0.975).setDamping(true).setBounce(1).setCollideWorldBounds(true).setCircle(200).setScale(.2).setInteractive();

ball2 = this.physics.add.image(160, 250, 'redBall');
ball2.setDrag(0.975).setDamping(true).setBounce(1).setCollideWorldBounds(true).setCircle(200).setScale(.2).setInteractive();

this.physics.add.collider(ball, ball2);

If you have any ideas at this point...

The forum is now here.

Use matter. See this example.

Ok thanks, i'll repost my issue there so. I'd like to know why this is happening before switching to matter.
