[Removal of Transfer Window and Squad Resitrictions (FM19)]

Hi All,

I am trying to take the English lower leagues database, remove transfer windows and add 2 squad restriction rules, when i do this i keep getting endless errors when i test the database to validate it. However, if i add the database (as downloaded) to FM it works fine, i don't understand why me doing the changes above would affect the database and me receive messages "league xxx has too many promotion" Even if if take the base file and validate it without any changes it has errors also.

Any advise please?
