If you edit your file while your server is active and you're connected, your stats won't be updated. If you look at your code, you probably load the player's file (this is called caching) and store it in variables on the server and then save the data when the player disconnects - the problem here is that your file is not re-checked to reflect the changes on your file, so you need to disconnect your client from the server or use another name and then edit your file, save it and then reconnect to your server.
