(GMS2) Spawner object doesn't spawn items

In GMS2 I have a spawner item with the following code:

• In the create event:

  timer = 0;
  

• In the step event:

  if(distance_to_object(obj_coffe_bean) > 2) 
      if(timer == 200) {
          instance_create_layer(x, y, obj_coffe_bean, obj_coffe_bean);
          timer = 0;
      }
  else timer++;
  

This works perfectly fine, coffee beans are spawned when it doesn't detect any coffee bean nearby.

The problem is that the same code doesn't work when I duplicate this object and create a spawner for another item.

Ok, I needed to use instance_create_depth instead of instance_create_layer.
