Animation clip length returns 1 when I use animator from assetbundle

Unity Engine
1

foreach (AnimationClip clip in m_animator.runtimeAnimatorController.animationClips)
{
Debug.Log("name : " + clip.name + ", length : " + clip.length);
}

In this code, animation cilps length are all returns 1, but the names are correct. The animator is loaded from assetbundle. If I change the animator to the same one at Assets folder in unity editor, everyone is okey. What’s the problem? Is that a bug? or any other way to get correct length?
And also is there a way to see the animation states at an animator loaded from assetbundle? I can’t see anything on Animator tap from assetbudle. It just say “Cannot show controller from asset bundle”. Any release schedule to patch to show this?
Plz, answer. Thank you.
