Tutorial - Working with Components on Actors Part 1 -

I’m doing the tutorial: Working with Components on Actors Part 1

It says that DefaultSceneRoot is missing, but it’s not. When I click Next, nothing happens. (CHECK SCREENSHOT)

I assume the tutorial is trying to go to Part 2.

Working with Components on Actors Part 2

Part 2 wants me to add a Scene component, but technically the DefaultSceneRoot is the root scene component right?

Question: Is adding a Root Scene component and making it a child of the Base component no longer required as described in the tutorial, since DefaultSceneRoot remains intact?

Which is correct? This:

or this?
