Pre Game Editor Help

Hi everyone,

So I am using an 23/24 update from TheNotoriousPr0.

I am having a play around and want to have a fun last FM23 game before fm24 comes out

So I want to place Coventry City in the premier league, so I swap them with Sheff utd, save editor data and then load a new game.

Every time I do this, it just keeps putting Leicester city into the Premier League instead of Coventry.

Sheffield utd are in championship where they should be, Coventry though are in the championship and not prem, 

How do I go about sorting this out?
