Skin Turning Into Traffic Cone Things

My sister was on PS4 and I was on computer. Every custom-made skin (imported skins included) had turned into what she just called traffic cones. Any skins bought from the marketplace worked properly, but any other ones were that. Reinstalling MC, restarting MC, restarting the PS4, and things like that didn't fix it, so it's not like most visual bugs we come across.
