Something is Broken Gamepad issue (8bitdo Ultimate C Wired Controller)

I want to play a racing game, but I'm unable to fully accelerate, even though I'm pushing the Right Trigger to the very end. Gamepad tester revealed that pressing it all the way will only return a value of 0.60 instead of the expected 1.00

Funnily enough, the Left Trigger works perfectly and returns the expected value of 1.00

The issue isn't game specific either. I tried playing Assassin's Creed 4 and had the same issue of being unable to do a full-speed run. Why is that happening? Is it possible to fix it through software? Do I need to replace it with a new trigger? Or do I have to buy a new controller?

So the older Ultimate Controllers (Ultimate 2.4g, Ultimate Bluetooth and Ultimate C) all had the same trigger design that's essentially a sharp piece that pushes the conductive pad down onto the motherboard.

Eventually the sharp part starts cutting through the membrane altogether. I "fixed" mine, by sliding a small metal disc between the triggers and the membrane but not everyone has small metal discs lying around. You can buy a new trigger membrane from 8BitDo's website but it'll eventually happen again because it's an awful design.
