I got the same thing too. The problem I think is that the bill board material makes the leaves grow each spring, so will stretch out your textures and make funky things.
You have two options...
1 - change material to 'FoliageMaterial' which should keep them ever green and make them sway in the wind.
or
2 - Scale the faces with the leaves in your model down to about 1/10 of the size you ultimately want them to be. The game will increase the size as it needs to.
See this pic of my maple tree for comparison...

The large faces are bare branches, which are at 0,0 so they do not sway and will stay visible all year long.
The small faces are the leaves, these are full UV and will grow each spring, disappear in winter, and sway with the wind when using the billboard material.
Oh, and you might want to try to offset the UV placement of the leaves on channel 3 so that the center of the square is at 0,0 so only the top right 1/4 is on the map, like the images I showed in the last post. That might also be stretching out the textures in funny ways.
