Issue with custom Balkan Cup

Hi,

Hoping somebody will be able to help me here. I am trying to make a Balkan Cup knockout competition with 16 teams. 

I have set the nations up as follows:

The intent is to have 2 teams for Turkey, Serbia, Croatia and Greece with 1 team for the rest of the countries like so….

Everything  tested ok under the basic rules so I loaded up the game and everything. For the most part it worked as expected taking the champions from most nations and the runners up for Turkey, Greece, Croatia. For some reason though it is selecting KF Tirana for Albania despite Teuta being champions last year and it also passes over Red Star for Serbia and favours 11th placed Napredak. 

Does anybody have any ideas why this might be happening? I figured I would fix it by going into Advanced Rules and actually specify to pick the winners and runners up for the competitions but as soon as I go into Advanced Rules if I test I get a strange error message even if I have not made any changes. 

Does anybody know what causes this error and how to fix?
