Describe the bug

I'm trying to convert the following XML (https://github.com/iit-DLSLab/gym-quadruped/blob/master/gym_quadruped/robot_model/hyqreal/hyqreal.xml) in USD. With previous IsaacLab version, i was able to convert different model inside the same repo, but now, i obtain the following structure

(see hyqreal->base->base) whereas with the old IsaacLab version i was able to convert the model in a structure like this (see base->base directly):

Due to this difference, I think I cannot load correctly the usd in IsaacLab, since i obtain the following error now:

AttributeError: 'Articulation' object has no attribute '_root_physx_view'

I think this is the same error i see here: https://forums.developer.nvidia.com/t/error-please-ensure-that-there-is-only-one-articulation-in-the-prim-path-tree/311183

System Info

• Commit: c4bec8f and i tried even the last one 8f7f2b8

Thanks
