Dutch updates are not being installed (Win7)

Hello,
I tried WSUS Update 9.5.2 (and older) on various Dutch versions of Windows 7, but everytime I have the same problem: no Dutch updates are installed!
Language-dependent packages such as Internet Explorer are not updated at all. I made sure I checked x86 and x64 global.
When I check the file list I see that only German (DEU) are downloaded instead of Dutch (NLD)?
