Unity Export - Bones not recognized

Hello,
I’m trying to export for Unity. In Harmony everything looks correct, pivots etc. But when I import to Unity, the images are stacked, but the animation does happen. The images are all separate layers with game bone deformation on them. Any suggestions would be great. Thanks,
Fabrizio

I deleted pets / bones and redid it, seems to work fine now. Not sure what the problem was.
