Graphics not displaying updates

I have a lovelace configuration that has images that overlay each other depending on where someone is. So originally I had the base image and then other ones overlay it depending on what’s going on. So I accidently made the images transparent so where the overlaying image didn’t have content, you could see what was behind it. So I updated them all with a white background to mask things and it seemed to work but only half of them or images for one of the two people. Any idea why it’s not showing the updated images? Basically in /www/images or in HA terms /local/images

Thanks.
