UnknownFormatConversionException

Hello, I'm trying to replace strings! But when I change the prefix tag (%prefix%) to %prfix% it gives me this error:

This is my code:

Code (Java):

                    if(SettingsManager.getInstance().getConfig().getString("no_kingdom_msg") == null) {
                        SettingsManager.getInstance().getConfig().addDefault("no_kingdom_msg", "&c[&r%prefix%&c]&r &c[&r%playerdisplayname%&c]&r&0>&r %message%");
                    }
                   
                    message = SettingsManager.getInstance().getConfig().getString("no_kingdom_msg");
                   
                    //Replacing tags
                    if(message.contains("%player%")) {
                        message = message.replaceAll("%player%", player.getName());
                    }
                   
                    if(message.contains("%playerdisplayname%")) {
                        message = message.replaceAll("%playerdisplayname%", player.getDisplayName());
                    }
                   
                    if(message.contains("%message%")) {
                        message = message.replaceAll("%message%", e.getMessage());
                    }
                   
                    if(message.contains("%prefix%")) {
                        message = message.replaceAll("%prefix%", KingdomHandler.getInstance().getPrefix(player));
                    }
                   
                    message = ChatColor.translateAlternateColorCodes('&', message);
                   
                    e.setFormat(message);

 

@Mr_Minecraft15
Where do I need to put SettingsManager.getInstance().getConfig().options().copyDeafults(true);? Every time I use SettingsManager.getInstance().getConfig().addDefault();?
