Where is the LeftHand in the Raw Mocap Data for Mecanim Avatar?

I’m trying to understand the rig from the Default Avatar prefab from the “Raw Mocap Datafor Mecanim”. I got it from the Asset Store for free. I opened the “Configure…” scene in the Rig tab, and I click on the LeftHand in the Hierarchy, but I can’t understand where it is. I attached a picture below. Is the LeftHand the big red bone in the bottom left of the image, or is it somewhere else?

The LeftHand is here. I think because of disconnected bones the LeftHand Bone looks like is split into 5 bones to connect with the finger bones.
