[Plugin] Leap Motion - Event Driven

Hi, thank you for this great plugin.

I have a question about using this plugin with the Flex branch of Unreal: how do I make the left hand work with Flex objects?
I am using Flex UE4 + LeapMotion + Oculus DK2 to accomplish something similar to this: v=Fv9QGPCppwE.

I have created a new Game Mode blueprint that uses the LeapFloatingHandsCharacter pawn, as per the instructions.

When I try to interact with a flexSphere, only the right hand works:

Interestingly, the left hand collisions work with non-Flex meshes.

Does anyone have an idea what is wrong? Thanks
