Wrap mode doesn't work？

I'm using Transform Tween Track and wrap mode set to none.
But after timeline is over, I simply find my character can't move.

Also, while using Activation Track and Post-playback state set to Leave As Is,
when timeline is over, I can't change gameobject's active state through script.

Would be grateful if anyone tell me what's wrong.
By the way ,I'm using 2018.1.

 

I found that maybe has relationship with player's rigidbody constraints
