Preview Watermark after building

Hi all,
I am creating vr architectural space, I have read that I should use static lighting to save fps but, if so, I get the preview text in shadows and building the lighting is not removing it…I have only a sun and sky system, with the directional light set to static and the skylight set to stationary ( if I set this to static, the scene becomes very dark, like if the Indirect lighting were gone…). I have searched for a solution but found nothing…maybe I am not using the right words… Thanks in advance
