Hi @rnd_tr1,
Could you describe what you are running into more specifically? I don't know if it was you but we had another user bring this up and that's when I really understood the subtle issue you are running into. I believe @jesper8W75R has also run into a version of this.
Basically, right now it takes a lot of work to fully unlink a Team library from library.io. Even if you break the link at the library level the links at the individual 3D model level are still preserved. In order to fully break it you have to go into each individual 3D model, edit and assign new models to them. Our team is aware of this pain point and it's on the roadmap to provide a formal, easy way to fully schism the team library and the managed library from each other.
Any additional info will be welcome and will help us figure out what's going on.
Best Regards,

Jorge Garcia
