Croach in Gears of war 2

I have box x and i couldn’t croach down. I tried to push left thumbstick, but not working. I haven’t got this problem with ultimate edition. Somebody tell me please how croach in this game.

You can’t crouch in Gears of War while running or standing. First, you have to find a flat wall, then press A (green button) to get into cover and press left thumb stick to crouch. You can move along the wall while being in such position. To stand up again press left thumb stick again. If you would like to humiliate someone by t-bagging them, get into cover near them (make sure they are injured and in Down-but-not-out state) and keep rapidly pressing your left thumb stick
