Struggling setting up device

Hello all, I just bought 2 Thrustmaster T16000 joysticks. I want to play mostly Mech games with them. I set them up just now, installed drivers etc. "USB Controller Setup" recognizes the controllers and all buttons and sticks work fine. But when I launch any game I cant remap the controls. I tried Mecha Break abd Armored Core.

What did I mess up?
