Issue with Building a Custom Record Page for Lightning Experience Test

I'm having an issue with the "Building a Custom Record Page for Lightning Experience". I definitely have the right components on the lightning page layout. I think it might be the "Feed" component since there is no longer a "Feed" component it's now called "Chatter Feed". I tried it from a fresh organization with the same result. I tried creating a custom component named "Feed" but that failed as well, likely because of the namespace.
