League Separator Problem

I'm trying to make my own league where the top division is like the SPL, with 14 teams that will play twice then split into top and bottom to play each other twice again, only problem is I don't know how to use the League Separator, can anyone help me understand how to us it?

Anyone able to help? Please, it's driving me nuts!
