Pre-game Editor Help - Trying to delete youth team

[tejas]

I want to be Brentford and am trying to delete their youth team so they only have reserves like in real life. But nothing I try on the editor works in the game, they still have an u18 squad full of fake players. Is it hardcoded into the game that every team must have a u18 squad or something? Or can I do something on the pre-game editor to make it so I only have a senior squad and a youth team? 

 

Any help would be much appreciated. Cheers lads.
