1) Cutscene tracks can not be deleted if they are part of the prefab asset. As such, you need to delete the track from the prefab asset itself, instead of the prefab instance in your scene for example.
2) Hm..Can you please confirm that after the cutscene is finished, the Animator Component of your character is enabled?
3) This is a known issue. It’s not anything harmfull, but it needs to be fixed anyway 🙂
