Can't move collision component inside blueprint

Hey guys. I’m very new to unreal as you can probably tell from the question I’m asking. I’m trying to create a new actor blueprint which uses a sphere collision component as the scene root and 2 simple static mesh components (sphere and cylinder). However, the problem I’m facing is that I can’t edit the scale property of the sphere collision component without it affecting one of the other components in some way and I also can’t seem to move the collision component around at all. What could I be doing wrong?

The collision component is most likely the root component, you will have to change the hierarchy of your actor components so something else is the root
