Collision meshes not following animation

I have this door, sliding open from the middle and out to the sides. The collision meshes are supposed to follow the door when it opens, and they do in ShowTool, but you cannot walk through in-game.

I have animated the col-meshes directly since that was what worked with my previous gate. What could be wrong?
