Invisible file attachments in library submissions

Hey admins, I attached PDFs to both of these submissions, but can't see them.

http://libcom.org/library/%CE%AD%CE%BA%CE%BB%CE%B5%CE%B9%CF%88%CE%B7-%CE%BA%CE%B1%CE%B9-%CE%B5%CF%80%CE%B1%CE%BD%CE%B5%CE%BC%CF%86%CE%AC%CE%BD%CE%B9%CF%83%CE%B7-%CF%84%CE%BF%CF%85-%CE%BA%CE%BF%CE%BC%CE%BC%CE%BF%CF%85%CE%BD%CE%B9%CF%83%CF%84%CE%B9%CE%BA%CE%BF%CF%8D-%CE%BA%CE%B9%CE%BD%CE%AE%CE%BC%CE%B1%CF%84%CE%BF%CF%82-gilles-dauv%C3%A9-fran%C3%A7ois-martin

http://libcom.org/history/revolutionary-defeatists-greece-world-war-ii-aghis-stinas

The files are still present, at http://libcom.org/files/GrEclipse.pdf for the Greek version of 'Eclipse and Re-emergence', and http://libcom.org/files/stinas_mem_en_v0_95.pdf for the Stinas piece, but for some reason they don't show up on the actual library articles.

Any idea how to make them visible?
