Linked objects bring un-existent camera and sun to my new scene?

Hi. I am using blender 3.0 today date. I am linking a collection from a file saved in 2.93.4.
When I link it to my new scene in 3.0 the collection comes with a camera and a sun attached.

There are no sun and cameras in the ref file …is this a bug? I am new to using linked meshes, so It is possible I am missing something here and blender versions are irrelevant with this issue.

Thank you
