Lower and upper head races turning with fork.

both the upper and lower head races are moving when I turn the fork. The crown race is snug. I tightened the lock ring just so the fork rotates freely without any other movements. Is it safe to ride, how do I stabilize the head races?

Thank you!

See parts diagrams above.

Crown race, adjustable race, and locknut are supposed to turn with fork. Lower race, upper race are supposed to be fixed to frame. Is this what is happening?

Excellent exploded view given above for you, you've not mentioned any details on the bike type, the above view is true for general road bikes & many earlier MTB bikes.

The forks are offset forward, so try lifting the bike so the forks through the stem are 90. degrees to the ground, is the movement smooth from each side to the other, not pinching, you may have something like a a bearing retainer broken segment ?

If what you are saying is true then you need to fully disassemble and measure everything up and determine the issue. Depending on the bike it is possible someone has put the incorrect parts in. Otherwise you will have to try Locktite.
