CUDA Nsight Systems not outputting CUDA Traces

I am trying to check whether my kernel and memcpy runs concurrently on two GPUs or not. So I am using Nsight Systems 2019.3.3 and run the .exe of my CUDA project written with Visual Studio 2015 with it. I have all options within the project enabled so that I can be sure that it should output CUDA Traces. When I began with profiling, some runs had CUDA Traces and some didn’t, to me for no obvious reason. But now, I can’t get it to output them anymore.
