How to get rid of old Onenote files in Onedrive

I've been using Onenote for many, many years and over that time I have collected several unused files that seem to be un-deletable on Onedrive. I have deleted some of them within Onedrive from time to time but the names seem to remain. Here is what I see. When I click "Files" in One drive I see folders and under that documents which contains my only current Onenote database. The one I use. But, then I click "home" and see six old unused data base files that cannot be deleted. When I click on some of them the screen says "Sorry, something went wrong - Item may have been deleted by another person" Another file will say "This item might not exist or has been deleted". I am the only one who uses this account.

I'm not sure what HOME is or what its function is as it doesn't show any folders or files that are active. It only shows these abandoned Onenote databases that nothing can be done with.

So, Is there a way to clean this up or is it just not worth the effort. Since I don't know what the function of Home is I'm not sure if it matters.

Thanks for any enlightenment.
