I like to keep my list of shared PDF list clean. Can't remove old shared PDFs!!

I have 4 or 5 items on my list of shared PDFs that have long been deleted (almost a year since last active).

Back when I deleted this shared file I must had done it incorrectly, it still shows up as an item on my shared list. How can I get it removed?

I would like to follow up with I have selected them both individually and as a group and selected "Delete Shared file" and i get an error. "FAILED TO DELETE SOME FILES"

I assume because they don't exsist.
