Hey guys,
I've noticed that when viewing Assets.xcassets that some images have certain versions of said image highlighted with a grey background (e.g. the @2x version of an image has the background, whilst all other versions don't). I'm assuming Xcode is trying to tell me something by highlighting the file, however, I can't seem to figure out what the issue is. The image seems to display ok in the app on the phone, but I'm concerned there's some issue I'm not aware of. I've included a link to a screenshot. The images are JPG format.
Any help as to what this grey background means and how best to remedy it would be much appreciated.https://ibb.co/j2uBiH
