USphereComponent can't AttachTo RootComponent

I’ve been trying for a while to get a USphereComponent to attach to my root component.

Every time I start the game I’m told there’s a:

“Template Mismatch during attachment. Attaching instanced component to template component. Parent ‘CollisionCylinder’ Self ‘AOE’”

.h

USphereComponent* aoe;

.cpp

aoe = CreateDefaultSubobject<USphereComponent>(TEXT("AOE"));
aoe->AttachTo(RootComponent);
aoe->SetSphereRadius(1000);

What am I doing wrong?
