Shot added to level sequence plays in Unreal Editor, but doesn't appear in final AVI render!

Can anyone see what’s wrong here?

I just added another level sequence as a shot to my current sequence, as that added shot only contains animation data imported via Datasmith.

In Unreal, when I click on my camera rig rail, I can see the included sequence animate fine, but when I open the AVI file result from the render, the camera rig rail movement is there, but the extra included sequence shot animation is not.
