Fresh scraping marks on caliper bracket where brake pad ears go?

I noticed some fresh scraping metal on metal markings on my caliper bracket where the brake pad ears sit in place. I can hear the scraping when I drive and it goes away when I press the brakes. Also, I hear a bit of grinding when I release the brake pedal, never when I press the brake only when I release the brake. I did have the brakes apart and put some anti seize lube on the fresh metal marks and it took the noise away for roughly 1 week. Is this brake drag or just not lubricated with the proper grease. The marks are only on the left side of the vehicle and only 1 spot where the brake pad sits. I will mention the pads and rotors are brand new and calipers are in good shape. I just had it for a drive and the scraping or rattle goes away when I touch the brakes slightly.
