Miniature trees in terrain editor

I’ve downloaded the Terrain Assets from the Unity website to try out with the terrain editor. When I add trees, I get miniature trees that I can’t see. To solve the problem, I tried scaling the prefab tree 80X and I also made the terrain reload the assets. It still doesn’t work. I alway get miniature trees. If I add a tree manually in the scene, it works perfectly and it’s size is good, it’s only the terrain editor that doesn’t work with it. Can someone tell me what I’m doing wrong please.

NOTE: This only happens when I add the “banyan” tree from the terrain package. If I add the other trees from the standard and terrain packages it works fine.

I found out I have to burn the size in the file to 1 with C3D’s CoordSystem in the tools menu. It worked after that.
