400ex axle issue

Bought a 2002 400EX a few months back and noticed the rear axles had a couple of washers on each side. Figured it was someones attempt at making it wider.

When I went to remove them it turns out the axle splines are too long and the axle nut won’t cinch down.

As far as I can tell they are all factory parts. Looking through the parts diagram it doesn’t look like there should be any spacers here, so what am I missing? Almost like the wheel flanges are too short. This is where they would need to be for the axle nut to work.
