Help required for FM18 Editor Advanced Rules

[allstar56]

I am trying to remove the relegation/promotion play off systems across all French leagues in the FM18 editor. Sadly, after months of trying I am unable to. All I would like is the following structure:

Ligue 1: bottom 3 teams relegated to Ligue 2
Ligue 2: top 3 teams promoted to Ligue 1 & bottom 3 teams relegated to National Championship
National Championship: top 3 teams promoted to Ligue 2 & bottom 4 teams relegated to Amateur National Championship

I have been hit with error message after error message regarding incorrect number of teams across leagues, and most recently that the dates for Ligue 2 fall outside of season update. I live in South-West London and at this point, I would be willing for any skilled FM editor who believes that they can help me with this issue to come over to my house and solve this issue for money. Name your price. Flat fee or fee p/h, I don't care! 

Thanks
