To reproduce:
1. Open the attached project;
2. Open "test" scene (Assets > MainScene > test);
3. Enter Play mode;
4. Open the Animator Window (Window > Animator);
5. Trigger "jump" parameter in the Parameters tab;
6. Check XYL Game Object's Y position change after playing the animation.

Expected result: Game Object Y position returns to a starting position after playing an animation.
Actual result: after playing an animation, Game Object does not return to 0 position on Y axis.

Workaround: Bake into Pose the Root Transform Position (Y) of the Animation (Assets > Resources > ArtWork > Player > TestHero > @runJumpFar00 > Edit runJumpFar00 animation clip > Root Transform Position (Y) > Bake Into Pose (true)).
