Gap between internal cartridge headset and fork
Some forks have an integrated crown race, and yours is one of them. 


When you get a new headset for use with such a fork, you leave the crown race out. 

Some sources imply the existence of 36° integrated crown races, but all the ones I've ever seen are the common IS 45°. As long as you've chosen a non-weird headset, it should just work.

Do not ride it like you have it pictured. The crown race that's jammed against your fork could damage it. (It probably wouldn't, but don't risk it.)
