How to use two lightmaps?

Godot Version



Im making a VR game using the mobile renderer. I have a scene with a light map. I have two of these light mapped scenes in my main scene but only one of them will have lights at a time. When I turn one of the lightmaps off the other one turns on vice verca. Lightmaps have also just been really glitchy in general for me flashing on and off and turning off at certain angles. Any idea whats going on?
