Ss noted, when you switched forks, you never transferred the crown race from old to new. It seems as though you ended up wrecking the weather seal, though maybe not. However you need to transfer the crown race, then assemble correctly with or without the seal.
ince the race seems to overhang the crown, removing it should be easy. Set some sort of punch under one side and tap it upward. Then switch sides and working back and forth work the race upward keeping it squarish until it's free. Mounting is done with a piece of pipe slipped over the steerer and driving it down.
