Messed up account stats

[Frail]

So I've recently purchased the game on Steam and created a new account on it to start fresh, but the account I linked to Steam shows stats(top 10 killers, characters created) from other accounts. From what I can tell, unlinking an account from Steam and creating a new one is something that can't be easily done, so my question is: Is there a way to reset EVERYTHING on one account? I have since figured out that the reason this data was added to the account was because of my previous installation of the game, but knowing that doesn't really help me much as it stands right now.
