OnTriggerExit being called by collider not marked as trigger error Unity

I have a hirarchy like so:
enter image description here
in the parent i have a the following components:
enter image description here
the child called DropDetector has a collider marked as a trigger. and the child called drop_area also has a collider but this one IS NOT marked as a trigger. But at the moment my OntriggerEnter and Exit functions are being called from the drop_area collider eventhough it is NOT marked as a trigger. Why is this happening? And how do i stop it from happening?

The DropArea script and rigidbody are attached to the parent called IncrementA_DropArea

If anymore information or clarification is needed pls let me know so i can clarify!

This is working as intended. From the unity docs on MonoBehaviour.OnTriggerExit(Collider):

This message is sent to the trigger and the collider that touches the trigger.

You can not avoid this from being called on drop_area's MonoBehaviours.

However, in the implementation of MonoBehaviour.OnTriggerExit(Collider), you can check first if the called MonoBehaviour's collider is not a trigger, and exit the method if so:

public Collider myCollider;

...

myCollider = GetComponent<Collider>();

...

void OnTriggerExit(Collider other) 
{
    if (!myCollider.isTrigger) 
    {
        return;
    } 

    // Do stuff for trigger here.
}
