I've got the same issue. I'm currently an 11th prestige/ level 24, but my elite page still has my custom classes from when I was 10th prestige/level 71 - about a month and a half behind. And, I can't update page itself to reflect my current loadouts because I used the prestige token to unlock a 7th class; the page has yet to recognize/acknowledge I've got it.
I sure hope they'll get it updated soon.
Keep your powder dry,
