Let me guess - when you say 'hanging off in the middle' - you mean off to the left hand side as you're stood in front of the car?
They all seem to do it. My '54 plate is like that. Jain's '05 plate didn't come with the splitter initially, but after it was fitted by Reno, it hangs off slightly - exactly at the same point mine does!
Mad Frenchies - can't even curve a piece of plastic correctly....
