Most of the locking nuts I have seen have a "shelf" on the top that will allow the nut to go so far. What this implies is that there is more space than previously between the fully threaded lock nut and the threaded race.
The first thing I would check is to make sure the locking ring is not bottomed out. If it is, then the issue is what is missing that was there before. Are all the parts assemble correctly? I can't imagine not given there is more rather than less space. The only thing I can think of is that there is a second spacer missing.
If it is not "bottomed" out, what are the conditions of the threads? Some times the tab on the spacer or cable stop bracket, if there is one, hangs on thread edges.
Does the HS rotate per your expectations?
