Applications like LibreOffice use the GNOME print dialog. You'll need to file a bug, either with the application developer (http://www.libreoffice.org/get-help/community-support/) or with GNOME itself (http://bugzilla.gnome.org)

Well, the output you included would appear to be incomplete, but the printer-uri-supported values point to different print queues with slightly different names (underscore vs. dash).
Look for the IPP_TAG_ZERO groups (or NULL names) in the attribute list - those are separators between groups of the same type.
(it would also be useful to know what Linux distribution you are using, and whether you are using stock CUPS or the distro-provided patched up version...)
