Physics2D.OverlapBox not working as expected.

Hello all. I'm trying to spawn game objects around a tilemap by checking if the object will not collide with anything before placing it. I essentially have a Decor object that contains the Required Size of the Object prefab it holds. For some reason though, Physics2D.OverlapBox() does not return a hit even if the box overlaps the walls, which have a TilemapCollider2D with a CompositeCollider2D. I've been searching for hours to find a solution, but nothing so far. I have the composite colllider's Geometry Type set to Polygons, since the Outlines mode only creates EdgeColliders that are infinitely thin. I even tried Outline mode and setting the EdgeRadius to something ridiculous like 20 and still nothing. Any help is appreciated.

Decor.cs

  public class Decor : ScriptableObject
     {
         public Vector2Int RequiredSpace;
         [Range(0f, 1f)]
         public float Chance;
     
         public GameObject ObjectPrefab;
 
         public bool CanPlace(Vector3Int pos)
            {
                var temp = new Vector2Int(pos.x, pos.y);
                return CanPlace(temp);
            }
         public bool CanPlace(Vector2Int pos)
            {

                 var newPos = pos - (Vector2.one / 2);
                 var hit = Physics2D.OverlapBox(newPos, RequiredSpace, 0);
                 Color color = (hit != null) ? Color.white : Color.green;
 
                 Vector3 temp = new Vector3((float)newPos.x, (float)newPos.y, 0f);
                 Debug.DrawLine(temp, temp + Vector3.up * RequiredSpace.x, color);
                 Debug.DrawLine(temp, temp + Vector3.right * RequiredSpace.x, color);
                 Debug.DrawLine(temp + Vector3.right * RequiredSpace.x, temp + (Vector3.up + Vector3.right) * RequiredSpace.x, color);
                 Debug.DrawLine(temp + Vector3.up * RequiredSpace.x, temp + (Vector3.up + Vector3.right) * RequiredSpace.x, color);
                 Debug.Break();
        
 
                 return hit == null;
 
 
           }
     }

And the following is the code I'm using to place the objects:

     foreach (var pos in floors.cellBounds.allPositionsWithin)
     {
         if (floors.HasTile(pos))
         {
             float roll = Random.Range(0, 1f);
             if (roll <= decorDensity)
             {
                 foreach (var possibleDecor in obstructiveDecorations)
                 {

                     roll = Random.Range(0f, 1f);

                     if (roll <= possibleDecor.Chance && possibleDecor.CanPlace(pos))
                     {
                         
                         Instantiate(possibleDecor.ObjectPrefab, pos, Quaternion.identity);
                         break;
                     }
                 }

             }
         }
     }

When Testing for the writing of this post, I actually can't tell what's going on because it seems like it does sometimes return hits and sometimes it doesn't. See the second image what I mean.

Firstly here is my Tilemap setup:

And here is a run. Successful placements are in green, failed ones are in white.
