Hi Swimm. I had this problem a while back and found for myself.
Seems it was SRS causing the issues with the Option " Allow More Input Devices " being the problem. This option needs to be turned to OFF. I have since done this and problems corrected. Just for anyone that was having the same problems as myself, with the Twist Grip -Rudder and Mini Joystick C ghosting. the problem was SRS if you are using it. Well for myself anyway. I posted this in Introducing Logitech X56 forum post back in 2019.
