Knoppix 3.7 Dual Language??!!#

I downloaded the 3.7 iso, the english version, after I burned it and ran the live cd everything looks fine. I then proceed to install it to hd. After I did this I booted up the system and half the menues and icons are in english and the other half (or better) is in german. What gives here??

I jsut ran the live cd and hit f3 and typed knoppix-lang=us just to be on the safe side. Then the hd install, and finally the system is all in english. Must just been a weird fluke
