I am new to Unity. Am taking the Pluraisight course called Unity 2018 Fundamentals. I am on a tutorial in the course describing how to create a prefab. I watched the instructor drag an object onto the scene and it shows the transform gizmo on the selected object, in this case a partial floor object, and he is rotating it. I followed along in my scene and dragged that floor object in but no transforms can be applied either through the keyboard short cuts W-E-R or selecting them from the menu bar. If I click-select on an already existing object like the massive floor structure below that Floor tile then the transform gizmo appears. How do I fix this? I have followed the tutorial very closely, pausing at each step and repeating when necessary. But I see nothing that I am doing differently from the instructor. Here are two screen grabs, one showing the small object selected with no gizmo and the second showing the large object below that has the gizmo. Here is a Screengrab from the video showing the transform gizmo appearing on this selected object.
