Problem/Bug (PEX) Rank Suffix Priority Messed Up?

So, I've been trying to fix this problem for a while. Whenever I promote someone to the Mod, VIP, MVP, or Skrub rank, the "[Starter]" suffix takes priority over it. I don't know if I messed something up or if I'm just blind, but I can't see the problem with the priority weights. Please help me fix this; it would be greatly appreciated.

You made vip inherit starter which has the starter suffix. You did not make a suffix for viper. If you make a suffix for every group, every group will have a suffix different from each other.

 

Ah, thank you. It works now.
