Problem
You are destroying the last spawned GameObject, which you keep a reference to in the enemy variable.
Solution
You should destroy what you hit. Unity3D already gives you who you collided against so just use that information.
function OnCollisionEnter2D(coll: Collision2D)
{
if(coll.gameObject.CompareTag("enemy") && jumped==true)
Destroy(coll.gameObject);
}
