I recently purchased one of these. I thought after you locked it down it could be turned on and looked like it was lit. That was not the case. Today I see that there are 2 for sale. One has the non-lit graphic like mine and is called a Incense Burner and the other has the lit graphic and called just Incense. Are there 2 different versions of this or is there something I am supposed to do to turn it on ? Thank you.
