WindDirectionalSource not affecting Speedtree content with Matinee "Movie"

Hello Unreal community,

I have really been losing some sleep over this, any assistance would be highly appreciated.

I have set up a scene in UE 4.11 Preview 5 with Speedtree trees and bushes as well as a WindDirectionalSource actor. Speedtree meshes were placed on a landscape actor using Landscape Foliage painting.
Speedtree content is not affected by the WindDirectionSource as soon as I start recording via Matinee “Movie” button. In any other scenario everything seems to be working correctly.

What could be causing this issue?
