Help with FM2013 editor

Hi guys, just wondering if i could ask a wee question. I started a save with Celtic and Rangers in the English Premiership using the editor.

For example i swapped Celtic with West Brom and Rangers with Stoke, and then i swapped Stoke and West Brom with teams in the Scottish 3rd Division, so Stoke and West Brom wouldnt be in Europe anytime soon.

Then after qualifying for Europe with Celtic in the Premiership i would never get in.......

Has anyone ever had this and if so do you know how to fix it because im clueless lol? Imagine there's something in the editor you need to change but im not sure, and there's no way of finding out unless i play a full season or two again haha.

If anyone knows cheers in advance.

you may start a game after you done with editor...do you?

Are you saying you finish in the top four of the Premiership, but don't get into the European competitions?

I'm not entirely sure, but you may have to change the nation of Celtic/Rangers to England, if you haven't already.
