If you did the prestige hack (to skip a prestige) and you did it before hitting Prestige 1 rank 69, you will unlock it when you next reach 69, the same with the 'schooled' thing at rank 65.

Which is the 1st Prestige?

1 > 70

or

1 > 70 > Prestige > 1 > 70

After you prestige once, that would be prestige 1
