OK. I know that list reads like a tech support call that starts with "Try turning off the power to your computer. Wait 30 seconds. Turn the power back on. Wait for the machine to boot. Are you still having the problem?" But it's always good to make sure the more common issues are out of the way and we're all on the same page before we start trying to dig into the really odd little corner cases.
I'll try clearing the gladiator badges on one of my characters and re-verifying them the next chance I get to see if I run into any issues doing so.
Just for the sake of comparison, could you link a character you're having issues with?
Edit: Oh, it might also be worth noting the version info Sentinel is showing.
