Stuck at SR-60, can't choose a specialization

When I hit sr-50, I chose Operator. After that, I entered in the experience codes into halo waypoint, boosting me to SR-57. Then, out of nowhere, I went up to SR-60 without earning any bonus XP. Now whenever I try to choose a new specialization I get it for about half a second before it sends me back to operator and tells me to pick again… I already deleted my title update and cleared my cache twice. What can I do to fix this?

Hi DarkLordRevan17.

Can you try deleting the Disc Two content from your console (War Games and Spartan Ops) and insert Disc Two to reinstall the content?

Thanks for replying, but I found out this morning that it was just the XP cap. I got at least 200,000 XP from the codes, so I just had to wait for a bit.
