After mapping the joystick in steam's big picture mode Arma 3 recognizes the stick, however sometimes it only sees one direction of each axis. So i can map for example the action "turn left" to "Axis X-" while turning the stick to the left. But when I try to map the action "trun right" to "Axis X+" while turning the stick to the right nothing happens.
Additionally in the case the axes are working correctly, pushing the stick forward is recognized as "Axis Y-". But when the odd behaviour occurs it is recognized as "Axis Y+". --> See appended screenshot, the white mapping is the right one. In both times the stick was pushed forward.
