Did you change your name?
I changed mine once played a few games and they showed up under my original account name.
Also I wouldn't worry too much about it currently, as they will be reseting the Pantheon when they fix the issues that are currently affecting favor, rankings, etc...
Basically if you have another account name try searching for that... If not, don't worry too much about it as it will be fixed soon, I'm sure, as of right now the stuff doesn't update accurately.
