Thank you for pointing this out. That is quite strange. Unfortunatelly we do not have a fix for this currently. What you can do is write a patch or you can go to admin tools http://www.epesi.org/Admin_tools and 'Run PHP command' to execute this code which wil replace the '\n' with a new line
DB::Execute("UPDATE utils_attachment_data_1 SET f_note = REPLACE(f_note,".DB::qstr('\n').",'<br />')")
