Halo 4 Armor - Disappearing

As you know, after leveling up in Halo 4 it will show what all you’ve unlocked. For the past couple levels it will show what I have unlocked but as soon as I go to look at it, it isn’t even there anymore. I sat on the phone with a Xbox Live representative for over an hour trying to fix it, but we couldn’t get anything resolved.

I could really use some advice and help on this one!
