Dan,
Is your suspension free and working otherwise?
When you push down on the center of the bike the front end may or may not compress due to the angle of force and the rear going down and also changing the rake.
The rake and trail in the front forks need a more direct frontal force to actuate. It works best when it comes to a bump head on so to speak.
So I found what you were talking about to be normal, but of course when you direct your pressure closer to the fork they should compress normally.
