Plutonium

Hello, i usually use Steam for my controller but rn it's no more possible to play with it so i decided to use SCP my PS3 works alright but L1 L2 and R1 R2 are reversed and idk how to fix it in Putonium. And when i launch the game the server appears but how do i get them back when i go into my class for example ? Thanks to those who will help me
