Yeah, this may be what's going on. You can check this by replying to one of the posts (but don't actually publish the reply). Your unsent reply will show the language code of the post you're replying to.

There used to be an automated language detection system, but very short posts or replies apparently caused problems as very short pieces of text can be difficult to reliably trace to one language.
