Custom Tree leaves doesn't work!

Hi i have a very strabge problem with unity 5. I’ve made my custom trees but i have a lot of problems that i can’t understand
The trees without leaves are loaded from the terrain engine, but the trees with leaves are only placed from assets view.
How can i feixed the leaves and the tree are different geometries

Custom tree have to match the criteria documented in the Unity Tree doc; see the section about Tree Creator and required material/structs.
