"Compiling Shaders for Deprecated PCD3D_SM4 Platform" Warning When Packaging

I get the warning “Compiling shaders for deprecated platform PCD3D_SM4” whenever I try to package for Win64 in both Development and DebugGame settings. I am wondering why and also how to change the platform because it lags a lot when it is trying to access cache data for that. Okay I am doing this on a laptop with only 2 cores and 8 GB of DDR4 RAM but this lagging is unbearable and it does not do that when packaging other projects.
