There seems to be a problem with the translation or the counting of Twenty Twelve strigs es_ES.

Mark that 71 strings are translated and missing one string to translate http://translate.wordpress.org/projects/wp/dev/twentytwelve, but if you browse to http://translate.wordpress.org/projects/wp/dev/twentytwelve/es/default?filtersstatus=untranslated&sortby=priority&sorthow=desc not leave any string to translate.

Is this problem of counting or does not show the missing one?

Thank you
