Phantom Controller Joystick Input,Phantom Joystick Input

I'm trying to use a controller for my game, but currently Unity constantly thinks that the left stick is being pressed up and to the right (printing to console shows it as (0.9,0.5)). Occasionally when I move the left stick it will display the correct inputs, but then immediately snap back to (0.9,0.5). I'm on windows 10, and I'm using a ps4 controller with Bluetooth, and I've tried both connecting it directly to my PC and emulating it with DS4Windows, and I get the same issue either way. When I used a Bluetooth Xbox One controller a few days ago I didn't have this issue, and I've changed nothing in the project since then. I'm using the new input system, and as far as I can tell, only the left stick is affected. All the threads I've found related to something like this (there aren't many) recommend just adding deadzone to fix it, but I'd much rather fix the actual issue if possible, especially since I'd probably have to add a massive deadzone. Is there any way to do this?
