Misleading locale choose menu
When users want to change the locale settings from manjaro-settings-manager, the menu pop up in a misleading way for languages without a region assigned (like eo.utf8 / Esperanto). For other language-region combinations like en_US.utf8 or zh_CN.utf8, after user selects the language, all available regions will appear:
While for Esperanto, though there is actually an "region" option available, it is a blank one, with no placeholders. It causes misunderstandings that the tool may not proceed with Esperanto selected.
Hence I suggest a placeholder like "No region" for languages of this kind.
