Files getting reseted

At my plugin I use more than 1 file and the 2nd file, does not work properly, here's my code

Code:

    FileConfiguration config;
    File cfile;
    FileConfiguration ranks;
    File rFile;
 
    public void setup(Plugin p) {
        config = p.getConfig();
        config.options().copyDefaults(true);
        cfile = new File(p.getDataFolder(), "config.yml");           
        if (!p.getDataFolder().exists()) {
            p.getDataFolder().mkdir();
    }
        rFile = new File(p.getDataFolder(), "ranks.yml");
        ranks.options().copyDefaults(true);
        if(!rFile.exists()){
            try {
                rFile.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

The rFile is created with nothing on it... here ar my save and reload methods

Code:

    public void saveRanks(){
        try{
            ranks.save(rFile);
        }catch(IOException e){
            ConsoleSender.Severe("Não foi possivel Guardar o ficheiro Ranks.yml");
        }
    }

Code:

    public void reloadRanks(){
        ranks = YamlConfiguration.loadConfiguration(rFile);
        Ranks.loadConfig(YamlConfiguration.loadConfiguration(rFile));
    }
