The DistanceCurveModifier generates Distance Curves with zero values for Root Motion animations

The DistanceCurveModifier data modifier generates curves that return zero values only. This issue has been tested on several Animation Sequences with enabled Root Motion and always occurred.

The DistanceCurveModifier generates Distance Curves with zero values for Root Motion animations

Reproduction steps:
1. Open a Third Person project template
2. Enable the Animation Modifier Library and Animation Locomotion Library plugins
3. Open a root motion-enabled Animation Sequence asset and ensure Root Motion settings are activated
4. Open the Animation Data Modifiers panel 
5. Add DistanceCurveModifier and apply it
6. Edit the Distance Curve

Expected results:
The values of the Distance Curve reflect Root Motion data from the animation.

Actual results:
All keyframe values of the Distance Curve remain at zero.
