getting a lot of Sensor issues

I got my Valve Index about half a year ago, It works fine then things starting happening to the Knuckles, the sensor on the left thumbstick stopped sensoring my thumb even for a gentle touch, the left trigger sensor causes my vr avatar model to curves it index finger to about less then 90* then the right thumbstick and trackpad stop tracking my thumb if I wanted to do a thumbs up gesture, is there anyway I can get these issues fixed up/repaired or do I need to get new knuckles?

Help me please
