Introduction to Unity TimeLines

I’ve been stuck for days on this video (112 intro to unity timeline) I do everything rick does but its not the same. for example when I create new timeline the red animation triangle is before my object ship and after my object ship is says (Animator) and on the video none of those are there and when I press the red dot for record a error message pops up in the console window (NullReferenceException: Object reference not set to an instance of an object
UnityEditor.EditorWindow.RefreshStylesAfterExternalEvent). please help , thank you
