With the Canvas selected, I attempt to add a button prefab using the Create shortcut. However, it always adds it as a sibling to the Canvas (the root of the Hierarchy), rather than a child to the Canvas. This is despite the Create setting in Preferences. I've tried changing that and it doesn't make a difference.
Adding GameObjects (sprites) works fine. Just appears to be when I attempt to add a Prefabbed UI element.
