Vray for sketchup batch render

batch render in sketchup is creating an output file for each light in my model. why?
​​​​​​​sketchup → batch render → i’m getting 46 files for each scene.
Each scene seems to be creating a render per light source in the model.
I’ve no idea how I’ve managed to do that - any tips please so I only get the finished rendered output file once?
