can´t removeChild with more than 2 childs

[casp0or]

Hi,

I am trying to add an enemy picture to my window, but also delete it from this window.

Adding is fine and deleting also ... but when i add a second enemy picture the second one gets deleted but the first one is not.

I have 5 enemy but only the last child is deleted -.-

    if(this._unitAdded[0].name != ""){
        this._enemy1 = new Sprite();
        this._enemy1.bitmap = ImageManager.loadEnemyPicture(this._unitAdded[0].name);
        this._enemy1.x = palceholder[0].x;
        this._enemy1.y = palceholder[0].y;
        this._enemy1_add = this.addChild(this._enemy1);
    }else if(this._enemy1){
        console.log("remove 1")
        //this._enemy1.opacity = 0;
        this.removeChild(this._enemy1);
        //this.removeChild(this._enemy1_add);
        //this._enemy1.bitmap = ImageManager.loadEnemyPicture("monster_empty");
    }

    if(this._unitAdded[1].name != ""){
        this._enemy2 = new Sprite();
        this._enemy2.bitmap = ImageManager.loadEnemyPicture(this._unitAdded[1].name);
        this._enemy2.x = palceholder[1].x;
        this._enemy2.y = palceholder[1].y;
        this._enemy2_add = this.addChildAt(this._enemy2);
    }else if(this._enemy2){
        console.log("remove 2")
        this.removeChild(this._enemy2);
    }

regards
