New Hongdui KM-17 Pro with extra cutter sizes. Shaft will not fit for extra size cutters.

So I got a new KM-17 Pro and the shaft does not fit for the extra size router blades that I ordered with it. I really like the router plane but having the blade kit incompatible out of the box is a real shame.
