Issue importing assembly with balljoint from OnShape into Isaac

I’ve been attempting to import a Delta Robot arm into Isaac Sim from OnShape. If the assembly includes a ball-joint, it will not import into Isaac Sim. The Onshape Importer appears, and it looks like its downloading, but nothing populates into the 3D workspace or tree. If I go back to OnShape, and change the joint to revolute, then it imports just fine. I’ve experimented going back and forth between joint types and the issue is repeatable. I’m not sure if I’m doing something wrong or if this is a bug in the importer.
