Skeleton bones in viewport not showing in 105?

I have Machinma 104 still loaded and I turn on skeleton bone view and can see the bones. This version uses SkelJoints under the Skeleton etc.

I load the same file into USD Compose 105 and turn on the same skeleton view but can see nothing. 105 however uses Omnijoints now, not SkelJoints. So I was wondering if the bone viewer needs updating as well to display the new bones approach in 105.

BUT! I just tried the Omniverse provided example for walking following path etc, and the bones showed up fine there. So its not completely broken (they are using Omnijoint too).
