Confused, how to remove stats from Novus?

[Steady]

I've read up the wiki and it said I need another Sphere Scroll. So I bought one but it has 0/75. Does that mean I have to start all over again to farm 75 Alex and Materias?

Current:

You take it to the guy at North Shroud, Jazahn, and he puts your old stats on it.... then you take it back to Huberwhatever and he can remove one stat at a time for you to add them back on after.
