Strange trigger collisions with 2D box & circle colliders

Hi, I was looking for a solution to this problem and came across this answer-

One of the comments towards the end was about how child gameobjects with triggers can activate the parent’s OnTriggerEnter functions. I do need the child to have trigger collisions, and I’ve narrowed it down to this collider messing with the parent’s. I was wondering if there was any way to let the child keep its collider but “unentangle” the colliders so the child and the parent have separate collisions.
Thanks for all the help!

U can add second Collider on GameObject with bigger Radius.
