Question OnTriggerEnter2D is called twice

Hello,
i have a bug that some times OnTriggerEnter2D is called twice, so enemy get double damage.
There is no second bullet spawning at a same time. I change their names with index.

Bullet code part:

Code (CSharp):

1.  private void OnTriggerEnter2D(Collider2D other)
2.     {
3.         if ((other.tag == "Enemy"||other.tag == "Player")& other.tag !=gameObject.tag)
4.         {
5.            
6.             if (other.tag == "Enemy")
7.             {
8.                 print("Hit!");
9.                 other.GetComponent<EnemyConfig>().DamageTaken(damage);
10.             }
11.             else
12.             {
13.                 PlayerConfig.HealsUpdate(-damage);
14.             }
15.             Destroy(gameObject);
16.             print("object" +gameObject.name +" destroyed");
17.         }
18.     }

 

So it really was because of two box colliders on enemy gameObject. But what can i do if i need one normal collider and one trigger (trigger is full size and normal collider at feet)? how cani ignore a normal one?
