Physics2D.OverlapBox and Physics2D.OverlapCircle keeps returning itself.

I am making a level editor and using the colliders to detect if there is any overlap before the item is place. I even made the added a layer mask as an argument and is returning itself that is not on that layer.

Code (CSharp):

1.     private void Awake()
2.     {
3.         collider = GetComponent<Collider2D>();
4.  
5.     }

Here is the main function

Code (CSharp):

1.     public bool CanPlaceObject()
2.     {
3.        
4.         if (collider is BoxCollider2D)
5.         {
6.             BoxCollider2D boxCollider = (BoxCollider2D)collider;
7.             if (Physics2D.OverlapBox(this.transform.position + (Vector3)boxCollider.offset, boxCollider.size, 0,3) != null)
8.             {
9.  
10.                 Debug.Log($"Cannot place box because of {Physics2D.OverlapBox(this.transform.position + (Vector3)boxCollider.offset, boxCollider.size, 0).gameObject.name}");
11.  
12.                 return false;
13.             }
14.         }
15.  
16.         else if (collider is CircleCollider2D)
17.         {
18.             CircleCollider2D circleCollider = (CircleCollider2D)collider;
19.             if (Physics2D.OverlapCircle(transform.position, circleCollider.radius,3) != null)
20.             {
21.  
22.  
23.                 Debug.Log($"Cannot place circl because of {Physics2D.OverlapCircle(transform.position, circleCollider.radius).gameObject.name}");
24.                 return false;
25.             }
26.  
27.         }
28.  
29.  
30.         return true;
31.     }

Here is where it's being called

Code (CSharp):

1.     void Update()
2.     {
3.         Vector2 screenPosition = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
4.         Vector2 worldPosition = Camera.main.ScreenToWorldPoint(screenPosition);
5.         transform.position = worldPosition;
6.  
7.  
8.         CanPlaceObject();
9.     }

 

Thanks for the response. What I mean by self is the logs are saying the overlapping area is the item that I am checking if has anything overlapping with it. Which I suppose makes sense, because I am checking the area based off the area of the collider that I happen to also to be dragging so it will always be overlapping. Noted on the feedback.
