Some animation clips do not show Clip Transform Offsets

https://docs.unity3d.com/Packages/com.unity.timeline@1.4/manual/insp_clp_anim_plyb.html

unity doc say that AnimationClips have Animation Playable Asset and Clip Transform Offsets.

Some animations do not show Clip Transform Offsets or Offsets Match Fields , Remove Start Offset.

I want to tweak these values.

What is the difference ? How to fix this?

Unity2019.4.3f1 timeline 1.4.1

The AnimationPlayableAsset does not show the offsets if the AnimationClip does not write to the root transform (either directly or with RootMotionCurves).
