Not the same trouble, you fixed the other one by finishing the commit, now you have a second problem.
In the previous exercise you added scene-3 and scene-7, in this one you were supposed to add, and then un-add, scene-2, with the end result that only scene-3 and scene-7 should still be staged when committing.
If you look at your screenshot, you'll see you did it the other way around.
Go back to the previous commit with
git reset HEAD^ and then add scene-7 and scene-3 and commit
