SR-130 XP bugged out on-site & in-game

On-site issue

When I try to look at my Career menu, I am told I have 20000 / 9223372036854437407 XP until SR-131 as far as I can see.

This didn’t happen before the statistics app update a few days back.

In-game issue

After entering one of the Classified Glyphs called ‘Curious’, I was given 20,000 XP for Halo 4.

However, now when I press Start in-game or visit various menus in lobbies, it says 20,000 / 0 XP instead of the normal 0 / 0 XP.
