Quotation marks changed after compiling into docx-format

I’m using smart quotation marks in Scrivener like this:
»Hello Schnuckibär.«
When I compile that into a docx or rtf-file this comes out:
“Hello Schnuckibär.”
The worst of that is, that the quotation marks at the front and back are the exact same. Otherwise I would have replaced them as a first workaround.

Not sure if this is a bug or if I’m doing something wrong.
