Tree creator, mesh leaves doesn´t show

I have modified one of my old trees. And have replaced the leaf mesh fort that. And now the leaves doesn´t show anymore.

I can see that the material already doesn`t get created proper when i use Mesh as the method for the leaves. Just the bark gets packed into this super texture. It works fine when i use Plane as method for the leaves though. I still hope that i haven´t picked up another bug here and that the issue is fixable.

Any idea how i can get this one back working, how i can show the leaves mesh at this tree here?

Have it. When i use a FBX mesh then it works. I use a Obj mesh here though. And this doesn´t show.

The Obj mesh itself works fine when i simply drag it into the scene. So there is a quirk with Obj and the tree creator i would say.
