Thanks, Lane.
I don't think I doubled up the colliders. For some reason when using a Character Controller, the object using the character controller can not initiate a Collision Event, only a Trigger Event.
In other words, if I shoot a rigidbody object at my character controller object, I can detect a collision using Collision Event on the "projectile" object.
If I set the "projectile" on the ground or suspend it in the air and run into it with a character controller collider, the bullet will not detect the collision nor will the character controller object detect a collision. This leads me to wonder if character controllers can only receive collision and not initiate a collision.
Another way of putting is,
Drop a rigidbody cube on the "Player" = Collision Event
"Player" jumps on the same cube ≠ Collision Event
Controller Collision Flags fire in the above scenario, just not a collision event.
I'll build a sample scene that demonstrates. Maybe there is some conflict I am creating with my Playmaker/Physics logic.
Thanks again for the input.
