Attack Overlapbox Not working

My Attack doesnt work like it should be, when i clicked the attack it damages the enemy even not being inside the collider. any help would be appreciated this bugged me for days

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Pointweapon : MonoBehaviour
 {
     [Header("Weapon Hand")]
     public GameObject _Weaponhand;
     public Animator anim;
 
     [Header("Dash")]
     public Rigidbody2D playerds;
     public float dashspeed = 500f;
 
     [Header("Attack")]
     public LayerMask _Whatenemy;
     public float _AttackrangeX;
     public float _AttackrangeY;
     public int _Damage = 10;
     public float _Gizmorange;
     [Header("Attack Timer")]
     public float _TimeBtwAttk;
     public float _StartTimeBtwAttk;
 
     private void Update()
     {
         if (_TimeBtwAttk <= 0)
         {
             Attack();
             _TimeBtwAttk = _StartTimeBtwAttk;
         }
         else
         {
             _TimeBtwAttk -= Time.deltaTime;
         }
     }
 
     private void FixedUpdate()
     {
         Pointer();
     }
 
     private void Pointer()
     {
         Vector3 _Difference = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
         _Difference.Normalize();
         float _rotationz = Mathf.Atan2(-_Difference.x, _Difference.y) * Mathf.Rad2Deg;
         transform.rotation = Quaternion.Euler(0f, 0f, _rotationz);
     }
 
     private void Attack()
     {
         if (Input.GetKey(KeyCode.X))
         {
             Collider2D[] _enemiestohurt = Physics2D.OverlapBoxAll(new Vector3(0,_Gizmorange,0), new Vector2(_AttackrangeX,_AttackrangeY), 0, _Whatenemy);
             for (int i = 0; i < _enemiestohurt.Length; i++)
             {
                 _enemiestohurt[i].GetComponent<Enemy>().Takedamage(_Damage);
             }
         }
         anim.SetTrigger("idle");    
     }
 
     private void dash()
     {
         Vector3 Dashpos = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
         playerds.AddForce(Dashpos * dashspeed);
         anim.SetTrigger("swing");
     }
 
     private void OnDrawGizmosSelected()
     {
         Gizmos.color = Color.yellow;
         Gizmos.matrix = this.transform.localToWorldMatrix;
         Gizmos.DrawWireCube(new Vector3(0,_Gizmorange,0), new Vector3(_AttackrangeX,_AttackrangeY, 1));
         //Gizmos.DrawWireCube(_Attackpos.position, new Vector3(_AttackrangeX,_AttackrangeY, 1));
     }
