Add nation rules

I’m looking for a bit of advice. Does anyone know why the add nation rules is greyed out? I’ve already changed some nation rules for a league I’ve created but I want to create another league and obviously I can’t because I can’t click on rules. any advice welcome 

I'm not sure if I've understood you correctly, but you can only edit one nation per file. If you want to edit another nation, you'll have to do it in another editor data file.

Perhaps give a tad more information as to what you did and now want to do

closing user been on forums and isnt updating thread as requested , PM if you want to provide more info in future and I will reopen this

cheers
