Custom Shaders Patch - Shadow Glitch??? Please help me out

[Shawniboy666]

So recently I uninstalled and reinstalled AC because I had to reset my content. When I started playing the game again using Custom Shaders Patch, I noticed there was a weird bug when I selected some of the cars. The hood of the car had become darker, which made it look kindof ugly. I tried reinstalling AC, Content Manager, and Custom Shaders Patch, but every time the issue came back. I only use Custom Shaders Patch to improve my FPS because I have a low spec PC.

This is what the car looks like when I deactivate CSP:

Any help will be very much appreciated.
