C++ UGameplayStatics Documentation?

Looking at UGameplayStatics | Unreal Engine Documentation, I see none of the static methods documented there. Why is this?

I can go to the header file and see them, but I’m just getting used to Unreal and am confused where they exist in the documentation. It makes me unsure as to whether or not I ought to use a method.

It seems that Epic’s documentation generator doesn’t show C++ functions that also happen to go to BlueprintAPI section of the documentation.

However even though UGameplayStatics doesn’t show list of its methods, the documentation for each individual method is generated in both C++ and BP version:

IMHO it’s a bug in how documentation is generated and I’d recommend filing a bug about it.
