C4D lite ground plane Issue

I started using C4D Lite recently as a 3d companion for After Effects.
I created a project using a 3d match move from AE and imported it into C4D.  I created an extruded title and applied the match move and it worked, except for one problem.  The ground plane lines show up when I export the tracked title back into AE.  How do I get rid of them?
Thanks,
Bruce
