I am doing the 2d roguelike tutorial to familiarize myself with Unity.

In the first part (https://unity3d.com/learn/tutorials/projects/2d-roguelike-tutorial/player-and-enemy-animations?playlist=17150) he is clicking a SpriteSheet in the project window (that has been imported from Asset Store) - He then gets a right pane in the project window, where he can shift click individual sprites to drag them to the Player prefab.

However, when I do this, I do not get that pane - I do get a preview of the sheet in the inspector - But I can't select in that one.

I can still make it work, but with a bit more hassle, so would love to know how to get that window/pane up - Any ideas?

EDIT: NM: I loaded the window layout default - and boom, now it looks right  Leaving the thread here if someone else have the problem.
