Are those sleeves Mylar? I have 4 mil Mylar holders on all of my prewar cards and they do not wrinkle like that. Looks like polypropylene (like a penny sleeve) or the cheapest possible 1 mil polyester film. I do share your frustration, though: this card annoys the heck out of me every time I look at the cheesy misfit sleeve SGC used
I'd get rid of it but they are rare as hen's teeth and I can't bust it out because it is too delicate to risk busting out and storing raw.
