Facebook stream - returns english only?


Hi All,
I am new to gnip and just create a simple csdl containing keywords as follows
interaction.type == "facebook"
AND interaction.content contains_any "Nestlé,Oppo"
AND language.tag in "en,id"

Why is the stream result is only in English?
Why I can’t get the messages in Bahasa Indonesia?
Is there something that I missed?

Thank you
