GPU Profiling - Scenes
I know it's late to answer this, but for future reference: It's because you have multiple cameras rendering, maybe you opened the GPU_Visualizer inside the editor and you have a camera spawned inside the level (maybe that of the player pawn) so you have 2 cameras (editor+pawn) so to say that the editor preview of the level counts as well.
