Hi Susan. It looks like a rep confirmed earlier this week that the site is experiencing a bug with the archive. You'll be updated via email once the engineers have found a resolution.
Unfortunately, I don't know if there's any other way to view the files that have been uploaded other than linking to a file and viewing the list of previously uploaded files. If you do this through an item description you will see the info in a larger box compared to the popup you see in the editor.
Click on Items>Item Library and add a new item (or edit one of your listed items). Type something in the short description, then highlight and click the link icon. Change the dropdown to "file" then click on the box that says "search existing files". A list of all the files you uploaded will appear, or you can search by key word. You can keep a list of files you need to delete as Adam suggested, and then you can submit the list to support with a request to delete.
