GPU is still not fully utilized

The result I got from the current version of Premiere Pro and the Premiere pro(BETA) when exporting is still the same. I am using my gaming laptop that has an NVIDIA GTX 1060 GPU and has my encoding set to hardware. however, when I press export, it is still utilizing around 16% of my NVIDIA GPU and 100% of my CPU. I also have my project setting set to GPU Acceleration (CUDA). I don't know what I'm doing wrong.
