In the Imsanity column in the list view of Media Library, for some of the files there is an option to Remove Original. For other files, there is an option to Remove Original Link instead. What is the difference between Remove Original and Remove Original Link? Remove Original works as expected, with the file being deleted and the reference to the file being removed from the attachment metadata in the database. However, I receive a “Removal Failed” error with the Remove Original Link option. What does the Remove Original Link option attempt to do, and what could be causing the error?
