Clip Sport Go doesn't show artwork

Recently got a used Clip Sport Go from a friend, it works really well but it won’t show artwork for some albums. I’ve got about 70 albums on it and it won’t show the art for about 20 of them, all of the other images work perfectly fine it’s just these ones.
I used TagScanner for editing them, format is ID3v2.3, all images are below 100kb and 400x400 pixels or below. I tried resizing, compressing, decompressing but nothing would work for these and I ran out of options.
