In project settings>input section, when you set inputaxis stuff for “gamepad right thumbstick X-axis / Y-axis,” labels are wrong. What it sets there for X actually plays through in Y, and vice versa.
Calls from stick input in blueprint (get gamepad right thumbstick axis) pull from correct axes, but “InputAxis X” and “InputAxis Y” call wrong if you label them according to project settings “labels”— seems it’s just a labeling issue in project settings menu.
