OverlapCollider not working from all sides

I am currently walking through a tutorial for making a topdown RPG, and have hit a bit of a snag. When using a OverlapCollider, it is not working from all sides, and which sides do and don't work seems to be dependent on the size of my boxCollider. The boxCollider itself is working from all sides.

The tutorial, currently at 1:47:00: [1]: https://www.youtube.com/watch?v=b8YUfee_pzc&lc=Ugx6PeznQ5HgdFMptGh4AaABAg&ab_channel=Epitome

In the current point in the tutorial, I have a script called 'Collidable' which can be assigned to an object in order to determine what it's colliding with. For demonstration of working it is logging the item being collided with (in this case the player), but when I do this it will only work coming from specific sides while it ignores others, and if I change the size of the boxCollider it will change the sides it works from, but no size will allow collisions from both x-directions to be seen.

Collidable script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [RequireComponent(typeof(BoxCollider2D))]
 public class Collidable : MonoBehaviour
 {
 
     public ContactFilter2D filter;
     private BoxCollider2D boxCollider;
     private Collider2D[] hits = new Collider2D[10];
 
     protected virtual void Start()
     {
         boxCollider = GetComponent<BoxCollider2D>();
     }
 
     protected virtual void Update()
     {
         // Collision work
         boxCollider.OverlapCollider(filter, hits);
         for (int i = 0; i < hits.Length; i++)
         {
             if (hits[i] == null)
             {
                 continue;
             }
             Debug.Log(hits[i].name);
             hits[i] = null;
         }
     }
 
 }
 

player script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Player : MonoBehaviour
 {
     private BoxCollider2D boxCollider;
     private Vector3 moveDelta;
     private RaycastHit2D hit;
 
     private void Start()
     {
         boxCollider = GetComponent<BoxCollider2D>();
     }
 
     private void FixedUpdate()
     {
         moveDelta = Vector3.zero;
         float x = Input.GetAxisRaw("Horizontal");
         float y = Input.GetAxisRaw("Vertical");
 
         // reset moveDelta
         moveDelta = new Vector3(x, y, 0);
         
         // sprite direction left or right
         if (moveDelta.x > 0)
         {
             transform.localScale = Vector3.one;
         } else if (moveDelta.x < 0)
         {
             transform.localScale = new Vector3(-1, 1, 1);
         }
 
         // Check if blocking item in path, move if not
 
         hit = Physics2D.BoxCast(transform.position, boxCollider.size, 0, new Vector2(0, moveDelta.y), Mathf.Abs(moveDelta.y * Time.deltaTime), LayerMask.GetMask("Actor", "Blocking"));
         if (hit.collider == null)
         {
             // movement
             transform.Translate(0, moveDelta.y * Time.deltaTime, 0);
         }
 
         hit = Physics2D.BoxCast(transform.position, boxCollider.size, 0, new Vector2(moveDelta.x, 0), Mathf.Abs(moveDelta.x * Time.deltaTime), LayerMask.GetMask("Actor", "Blocking"));
         if (hit.collider == null)
         {
             // movement
             transform.Translate(moveDelta.x * Time.deltaTime, 0, 0);
         }
 
     }
 }
 

Any help in understanding why I'm getting this result would be greatly appreciated.
