ParticleSystem>Collision: Max Collision Shapes fail for values greater than 1

1. What happened
ParticleSystem>Collision: If Max Collision Shapes is set to 2 or greater value, particles collide with all objects in scene.

2. How we can reproduce it using the example you attached
a. Open scene 3D
b. Select Particle System in hierarchy > Collision module
---> Notice the particles collide with all surrounding objects even though Max Collision Shapes is set to 2. Setting the value to 1 will cause particles to collide with 1 or 2 objects.
