That’s not what I meant. If you look at the boxes down the centre of the screen you will see that your joystick has 5 sliders, 1 coolie-hat and numerous buttons. The names in each of these boxes are those reported by your joystick so here you are creating a config file for a device that has two sliders called “X Axis” and “Y Axis”. The problem is that your mouse might also have two sliders with the same name so when you look for a matched device both the joystick and the mouse will match so you need to be lucky to get the right one.
My suggestion here is to create a link for the “Z Rotation” slider because mice don’t have these and just because you have a link doesn’t mean you have to use it in your sketch: 
Anyway glad the filter worked for you.
