My own Custom Story doesn't display on Custom Story Menu

[Bierton]

I have been working on my very first custom story and have followed numerous tutorials on Youtube to get it working. However, I have just finished the first level on it and I wanted to test it out to see if it worked properly. Problem is though the custom story is being displayed on the Custom Story menu in game. I've put it in the right folder and I have the custom_stories_settings.cfg file in which contains these codes;

<Main
Name="TheDarkestSecrets"
Author="Bierton"
ImgFile=""

MapsFolder= "maps/"
StartMap="entrance.map"
StartPos="PlayerStartArea_1"
/>
I've googled the problem and have tried numerous ways to fix it with no success. If anyone has any help that would be really helpful. Thanks
