VR dome light (green and white) only in one eye

[Jolk]

Hi All, 

At night when I switch on my cockpit green or white light, I can only see it in one eye, the other eye sees the cockpit with no light as if it was switched off.
i have a Reverb G2.

Are you facing the same issue? Or do you have an idea for a solution I can try?

Thank you very much for your help
