so after replacing my logitech g27 rotary encoder with the brass one because the plastic one snapped after playing like 8hrs straight my wheel decided that nothing on it wanted to work anymore, so my wheel was just sitting there for about 5 months or so and when the part arrived i replaced it and the wheel would not respond and i relised i hadn't installed it correctly so away i went to fix it properly and now the wheel wont stay centered and also i have no H-shifter or clutch on anything not just LFS if i move my wheel to the left then quick go to the right it would just lose the center alignment also there is a picture of the g27 in the profiler but theres no axis for a clutch and none of the buttons respond to any test in the shifter at all and i have tried to calibrate it but nothing happens, i hope someone can help me.

Ps. i hope you can understand it

EDIT: i managed to fix the calibrating problem by moving the encoder wheel closer to the infrared lights just the shifter will no work or anything just shows led.
