[Issue] Motion Link only animates Joint icon, not actual part in assembly

I've assembled an automotive differential (downloaded from GrabCAD) in Fusion 360 and have defined a number of rigid/revolute Joints and As-Built-Joints between the parts.  I'm now trying to establish a Motion Link between the pinion gear and spiral gear (which you can see in the attached movie and .f3z archive), and I can only get the spiral gear's 'flag-looking' revolute icon to spin with the pinion gear, not the actual spiral gear itself to spin with the pinion gear.  I checked the spiral gear's As-Built Joint and that the spiral gear isn't grounded or 'over-jointed' with anything else, as well as re-building the As-Built Joint and Motion Link several times.

 

Has anyone run into this problem before, and is there a fix to this or something I've done wrong up to this point?  Thanks very much for your help on this.

I got the joints working. What I did was delete the ground and motion link, moved the timeline back before revolute4, grounded the spiral gear axis, deleted revolute4 since there seemed to be a problem with that, created a new revolute joint to the spiral gear axis and the ring gear, then created a new motion link. 

 

Model is attached.

Thanks wmhazzard, this helped me resolve my issue.  I took a slightly different approach (grounded the Pinion Gear Axis and Spiral Gear Aixs, deleted the Spiral Gear revolute joint, recreated it, then created a motion link between the Pinion Gear and Spiral gear), but I am all set now.  Thanks again.
