Animator Motion Duration

[regrets]

Im having the same issue as Op using 2021.3.15f1. I created a new animation motion, duplicated it 3 times set each value to 1-2-3 respective and it says 0 in duration for each of them. I press save, select another motion and then back again and the duration now says zero.

Same motion in debug mode.

This looks like something different. I will split the thread.

What version of the controller are you using? The AnimatorMotion class is serialized with Unity's serializer so you could look at the asset file in a text editor to see if the changes persisted.
