Getting Errors in Grabber.h/cpp


So my code complies fine and everythings working,
but I started to realize that certain methods are being underlined in red as errors.

Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

trying to follow the descriptions I really dont understand as these are auto generated and I dont get whats going on. It suggestes I add a Macro to new C++ / hint file.

Is this something with C++ not recognizing the Unreal Macro APIs?
