The script found a DEFAULTSORT with lowercase letters at the start of one or more words, like {{DEFAULTSORT:Role-playing game}} or {{DEFAULTSORT:2004 in Film}}. Because of MediaWiki's alphabetization in categories, the first letter of each word should be capitalized. Write "Role-Playing Game" or "2004 In Film" for correct sorting in the category. (AWB, BOT).
