Not all patterns are automatically available in all languages.It always depends on whether the individual author of that pattern is able to provide it in several languages - there's no computer translating it automatically.
In general, a good indicator is the language of the description text itself - if that is in English, then the pattern should be as well. If not, then chances are the pattern isn't either.
During the checkout process it will be pointed out if the pattern you want to put is not available in your desired language.
If you are unsure about a specific pattern feel free to ask our support team via suppor@crazypatterns.net.
