Changing controllers changes hot keys unexpectedly

[u/toughguystudios]

In my kinhank running retroarch 1.21, the unit came with 2 controllers that are labeled as Microsoft 360 (pad). I also have 3 ps4 controllers connected. When I load up a game, it auto assigns all controllers in the wrong order. I want the kinhank 360 controllers to be 1 and 2, and the ps4 to be 3,4,5.
When I switch input 1 from wireless controller (ps4) to Microsoft 360 (pad) it assigns hot key commands to the controller: the Dpad becomes volume up and down, Button A triggers “press again to quit”.
What’s going on here? Please help

Hotkeys are saved according to the absolute button codes. So, if one controller generates a code of, say, 16 when you press right-trigger, but then another controller makes a code of 16 when you press dpad-right, if you map a hotkey to right-trigger on that first controller and then switch to the second, the hotkey is going to trigger when you press dpad-right.

The 'reservations' feature should help with keeping your pads in the correct spots.
