I replaced my thumb sticks with GuliKit ones and now the left thumb stick constantly pulls diagonally down and to the left and unresponsive to other input. The weirdest thing is that the left trigger, when pressed down, will pull the left thumb stick even more diagonally down and to the left.

I’ve tried to press and hold the calibration button, but nothing is working. The right thumb stick, however, was replaced and calibrated no problem.

As another note, using a controller via Bluetooth has no issues, just the left thumb stick on the Steam Deck itself continues to not work.
