Terrain Tree Problem

Hello, I have an issue with custom trees where I will import the mesh from blender as .fbx. I will try to paint it onto the terrain and it will just spawn at a 90 degree angle on the terrain on it's side. This goes for all of the trees I paint on as well, I have made the shaders the occlusion leaves and bark and I made the scale of the model 1 in the inspector on the imported model. I have tried to rotate the tree in Blender but when it is painted on the terrain nothing changes. Thanks for any help.
