Burst / single fire weapons not working properly with PS5 controller

Thanks for reading-

When I try to use burst weapons or semi auto, the game does not recognize all of my trigger pulls. Almost as if I’m pulling too fast or not letting go far enough. It’s like the gun is jamming IRL. I’ve changed the deadzones (someone clarify which direction I should be sliding this in?) but it still happens. 

Even if I was pulling too fast, I should be theoretically able to spam the button faster than the gun can shoot and it would register the spammy inputs as soon as the gun was “ready” to fire again. That’s why it seems to be a dead zone issue, but I still haven’t resolved it.

I’ve seen numerous posts about this on different boards, with no real resolution other than “remap to R1”.
