Steps to repro:

1. Open attached project and 't1' scene;
2. Enter Play mode;
3. Select WindZone gameobject in the Hierarchy;
4. Input some numbers into either Turbulense, Pulse Magnitude or Pulse Frequency field.

Expected result:
Tree's wind animation behavior alters with respect to corresponding field change.

Actual result:
Tree's wind animation behavior doesn't change with respect to corresponding field change. See attached video.
The issue has a big negative effect on users, since it greatly limits wind animation's customization to only toggling 'Main' field.
