SceneCapture2D Show Flags not Available in Blueprint

I’m confused. As of 4.15.2 if you create a scene capture 2D actor, the show flags are available. If you then add a child component to your character blueprint for example, the show flags are not accessible in the character blueprint. Does this mean they stop functioning? Cause that’s my problem, the scene capture is ignoring the flags I’ve set. I was following a tutorial on YT where this is clearly working for the author of the tutorial which is why I’m really confused.
The tutorial in question is : *NOT WORKING* UE4 - "Texture Based" Mini-Map Tutorial // Adding the Mini-Map - YouTube

Apparently the show flags used to work in another blueprint but have been removed in later engine versions?
