Left Trigger Button Recalibration (Gulikit Kingkong Pro 2)

Using a Gulikit Kingkong Pro 2. Had an issue with my RT and replaced it with the trigger button from my old Gulikit Kingkong Pro, and did the same for LT.

I'm not quite learned and all the terms I came across I did in the course of trying to repair it, but basically LT is currently constantly soft-pressed even on neutral. Is my LT Potentiometer busted or is it because of the new button, because RT is fine in any case.

I was thinking of recalibrating it to have the current state be neutral, but I have no idea how to do so. Do you have any ideas, or is this a hopeless case? Is it potentially that the buttons from the original have a different magnet strength and I should glue that on the replacement buttons?

Any help would be appreciated. Thank you!
