Photoshop adding gray to layers
I was working on a file and all of a sudden all of these gray spots appeared on layers that do no have gray. It's hard to describe but below is a screenshot of an export less than one hour before the issue. Note the color of the car (no gray appearing)

I'm not sure what the issue is and I can't even come close to googling it. If someone could please help me resolve it I'd greatly appreciate it.
