UM Content Restriction settings missing from Media Library

Additional Details:

Previously uploaded and restricted media files are NOT accessible to logged out users, however, files are also not visible to logged in users when embedded on a page. I get a “Missing PDF File” notice.

New uploads are immediately accessible to logged out users. As the UM content restrictions are missing from the upload page, the only option to protect is to use the “Edit more details” link. The UM content restrictions are available on the media page but do not protect the content when selected. Files are still visible to everyone.
