:::Putonghua means common language in Chinese (well, in Putonghua), but when used in English it is used as the Chinese translation of Mandarin, and thus doesn't really give any extra meaning to the usage. What could be done is combining the script and vernacular sections (after all they go together) for something like "Official written language = Simple Vernacular Chinese" meaning the other template can be converted into "Official spoken language = Mandarin". The coding somehow caused regional languages not to be shown though, which is odd.
