titled as the "latest posts"

[Valdo]

I have a Dutch wrote in my forum with its original language, and everything seems ok except the "latest posts"

the discussion is this:
The College of youths near Bad Tolz and the school children

but titled as the "latest post" appears written as:
Old [langtitle = nl] Het in de buurt van internaat Bad Tolz voor Jongeren en schoolgaande ...

how to fix this?
thanks
