Delete neighbour tiles too

Phaser 3

Hi!
Im trying to write my own version of bomberman and I`ve got problem with explosion, which is deleting boxes correctly but unfortunatelly it kills its neighbours too (some of them, and not always…)

What I found is when overlap occurs it spot sometimes more boxes - why ?

Some of my code:
this.boxesLayer = this.map.createDynamicLayer(“boxes”, this.tileset, 0, 0);
this.physics.add.overlap(this.boxesLayer, this.explosions,
this.destroyBoxes,null,this);

 destroyBoxes(explo,box)
{
    this.boxesLayer.removeTileAt(box.x,box.y);
    
}

    explode(){
    let range = this.player.range;
    let x = this.x;
    let y = this.y;
    let step = 32;
    let boxRight = false;
    let boxLeft = false;
    let boxUp = false;
    let boxDown = false;
    for(let i = 0; i < range; i++){
        if(!this.scene.blocksLayer.getTileAtWorldXY(x + i*step, y) && !boxRight) 
        new Explosion(this.scene,x + i*step, y);
        if(this.scene.boxesLayer.getTileAtWorldXY(x + i*step, y) || 
 this.scene.blocksLayer.getTileAtWorldXY(x + i*step, y))
            boxRight = true;

        if(!this.scene.blocksLayer.getTileAtWorldXY(x - i*step, y) && !boxLeft)
        new Explosion(this.scene,x - i*step, y);
        if(this.scene.boxesLayer.getTileAtWorldXY(x - i*step, y) || 
 this.scene.blocksLayer.getTileAtWorldXY(x - i*step, y))
            boxLeft = true;

        if(!this.scene.blocksLayer.getTileAtWorldXY(x, y+i*step) && !boxDown)
        new Explosion(this.scene,x, y+i*step);
        if(this.scene.boxesLayer.getTileAtWorldXY(x, y+i*step) || 
 this.scene.blocksLayer.getTileAtWorldXY(x, y+i*step))
            boxDown = true;

        if(!this.scene.blocksLayer.getTileAtWorldXY(x, y-i*step) && !boxUp)
        new Explosion(this.scene,x, y-i*step);
        if(this.scene.boxesLayer.getTileAtWorldXY(x, y-i*step) || 
this.scene.blocksLayer.getTileAtWorldXY(x, y-i*step))
            boxUp = true;
    }
}

It even looks like my overlap function is used even if no overlapping is done :S
