Model Collision Problem

I am importing a .obj file from blender which has materials, made in blender. For some reason, when exported with materials and put into my game, I collide a ray with the root node and test to see if the geometry the ray collided with is the same as the model I imported. The problem I am having is that it thinks that the model is some sort of object node rather than a geometry. The ray collides with the geometry:

teacher-geom-4 (Geometry)

But the model calls itself:

teacher-objnode (Node)

Does someone have any idea why this is happening, what the cause is and how to avoid/fix it?

Probably it is a nodeā€¦
