Little Big Planet Mash-Up Pack (Texture Pack) doesn't work when selected as the Global Texture Pack

When selecting the Little Big Planet Mash-Up Pack as your global resource pack, it does not globally change everything as it should. (Menu, music, textures) and will only work if you manually select it as the texture pack for the world, meaning you cannot use it in friends worlds or realms without them selecting it to be shown for everyone via the world settings. This also affects single-player worlds, as you would also have to manually select the texture pack from the world settings for each world that you want it on instead of it, again, being globally shown like every other mash-up pack/texture pack.
