Moding Voter Groups UI problem

Hello today i started making a mod in wich i wanted to add new voter groups, but the problem is that the UI i mean the midlle table wich shows all the groups, dosenlt scale, so my newlly added groups are stuck under the popularity bar and go even further down on the TAX policies and it looks ugly. Is there a way to change that? I mean in the code? Or is it impossible to change?
