All my mods of weapon are bugged

[ArkHerms]

Literally this error happens to me with almost all the weapon mods that I install even if I only have one mod installed, it looks darker than it should or it turns an ugly black color. I use Vortex, if anyone knows how to help me I would appreciate it.

In the gun picture, the rag should be white
