Mobile Logo Not Displaying

Hi, I changed the logos on my site via customize > Site Identity and deleted the old logos from the media library but for some reason, the new retina/mobile version is not displaying on mobile view. Both new logos have different filenames to the original logos but when I use Chrome inspector the path to the retina version is still showing the path to the old logo filename. I've tried clearing caches etc. but still have the same problem. (See screen shot) Any idea how to clear this error. I've tried removing and re-attaching a few times.
