Mario Mash-up issue

I can't select the skins from the Mario Mash-up pack. They appear, but the "select this skin" option thingy is not working. It works for literally any and all other skins, just not any from the Mario Mash-up pack. I don't know if this is a glitch on my system or if it affects others, but this is annoying either way. Please fix it ASAP, I want to use the Mario Mash-up skins.
