We don't have an AnimationRenderer component.
However, are your Spine components using multiple materials? Are you on Unity 5.6 and up?
If so, you need to add a Sorting Group component. This is a known bug in Unity; not sure if they'll ever fix it since it's a 2D mesh quirk they seem to have introduced and it still exists in 2017.1.
If you are using a different runtime that uses a component called AnimationRenderer, we don't know how to support it.
