ive tried creating the ultimate english league. ive swapped all Premier, champ, div 1 & div 2 teams with teams of my choice on editor and saved as separate database. however when i chose to play the game it wont let my select england nation to play as. the tick box is darkened with a yellow triangle next to it saying a team found in Championship, league 1 & 2 with wrong nation set.

Go back into editor and all teams nation is selected as england. What am i doing wrong/or havent yet done. or can this even be done

please help guys
