My rank has a bug. It appears to have a soft rest.

This is the first time I played the MCC edition since Mid January. My rank appears to have bugged and entered a soft reset. I require 2+ million exp but I’m back at starting tier ranks. I still have all my previous unlocks, I still earn exp, and everything else seems fine. I’m bringing this to attention because obviously a Sergeant shouldn’t need 2 million exp, but because I will be obtaining season rewards that do not reflect my rank shown. My last unlock was the Air Assault Helmet which I think is tier 37 for references.

There is no bug here. As you reach a different tour, the amount of exp to rank up increases. When you got the swords behind your shield that means you reached the next tour. There are eleven in total.
