Physics2D.OverlapCircleAll returning colliders outside of the area

I'm using OverlapCircleAll to create a Black Hole effect in my 2D Rogue-LIke game but it seems like it is returning colliders outside of the actual area, im using a range variable both for the overlap method and for a gizmo and enemies outside of the actual gizmo gets affected by my black hole effect but actually in a reverse effect. Here's the code:

 void FixedUpdate()
     {
         Collider2D[] cols = Physics2D.OverlapCircleAll(transform.position, range);
         List<Rigidbody2D> rbs = new List<Rigidbody2D>();
 
         foreach (Collider2D c in cols)
         {
             Rigidbody2D rb = c.attachedRigidbody;
             if (rb != null && !rbs.Contains (rb)) {
                 rbs.Add (rb);
                 float dist = Vector3.Distance(c.transform.position, transform.position);
                 Vector3 v = transform.position - rb.transform.position;
                 if(range >= dist)
                     rb.AddForce (v.normalized * (1.0f - dist/range) * gravityPower);
 
 
 
 
             }
         }
     }
     void OnDrawGizmos()
     {
         Gizmos.color = Color.cyan;
         Gizmos.DrawWireSphere(transform.position, range);
     }
 }

I managed to fix it by adding the if-clause before the addforce line but the fact that I had to do that shows that it actually returns enemies that are outside of the range of the overlapcircle since their distance from the gameobject is longer than the range I gave as an argument. I'm having the same issue in some of my other abilities where enemies outside the area are effected and I don't understand what could possibly be wrong.

Here's an example of what happens without that if-clause in place: https://gyazo.com/77473f8cebd3ed71d80a82d7fa2c864a
