Floor and floor reflections randomly turning on and off when rendering PV360

So I have rendered plenty of models on SW14 with floor reflections however sometimes they just don't appear for some reason. Then when I open the exact same assembly later on the floor reflections are visible. It seem random as I'm not changing any settings. (It might be worth noting as well that the actual floor isn't visible either)

Does anyone know why this would be happening?

Thanks,

Jacob
