I'm sorry I didn't find this option you mentioned about "Editable children from collision group".
I did check all of the options in the plugin docker. Do I have to disable that option in the .gd script?

Im pretty my issue is caused because of that. Somehow if the child (ex; the mesh) has same name as other prefab with the same name of the child, it causes that error. It gave error for another object with same name for AudioStreamPlayer3D. 
Which is strange, because they have their unique parent name and somehow this causes the error.

How I reproduce this is just use the plugin with .tscn files to place assets. It works fine at first. I might even try the game and everything is fine. After a while that error pops up, usually when reopening the scene that I am working, those meshes are doubled. I use Godot 4.6.

It seems like the "mesh" itself is one and another duplicate is in the parent. Because If I move the parent/root node, I can see only one, but if I take the mesh node, it moves away but there is duplicate at the root. (this shows in the game too and both will "work" in the scene as unique rigidbodies).

If I try make this before the error and I move only the mesh, the root does not have another mesh and works correctly. 

If I just could find the option to disable "editable children", It would most likely fix the issue. Thank you for your help!
