Any ideas? And what is the purpose of this pose?

Thanks,

That is a setup Pose for Steve's Hand Gizmo, it doesn't need to be edited or turned off. The "Left/Right_Finger_End_Joints_Bend_N_Y" Poses can be adjusted to vary the amount of bending the Hand Gizmo will apply to the second and third joint of the fingers.

Hope that helps, Rusty.
