Currently there is a bug on using multiple joysticks at the same time, at last when mapping,
but there is a workaround:
- Plug one controller and map it normally
- duplicate the controller in the mapping window
- remove the controller and connect the next one
- map it as the first controller
When using, connect the controllers and enable the preset normally,
if the mappings are inverted, keep the preset enabled and remove both controllers, then connect again in the desired order, it should work.
Sorry for the inconvenience. It will be fixed in the future.
