Gan i3 only two center lights come on

After having not used it for a while, doing a few turns only two corners of the white center internally line up. I am pretty sure all 4 corners used to light up. I wonder if anyone has experienced this or has any troubleshooting advice.

So I asked TC and they told me as far as they know there is only one light inside. So maybe I remembered wrong.
