Collider detects ONLY OnCollisionEnter2D ?

one collider collides into another but only OnCollisionEnter2D gets detected and keeps steadily increasing.

BUT OnCollisionExit2D and OnCollisionStay2D DO NOT GET DETECTED. I have no idea why this is happening. I tried manually moving the colliders together and separating… nothing…

Pretty sure OnCollisionStay detects it as soon as it stays for more than 1 frame, as in
I think OnCollisionEnter detects the very first moment or frame it enters or touches, and
OnCollisionStay detects how many MORE frames it was touching (so it detects after the first collision) I could be wrong though.
