Some Skin Packs Won't Preview in the Skin Chooser.

I was browsing the skin chooser seeing all the skins they have to preview in the marketplace. When I scroll down even more, some skins have to load for a bit. But the more I wait or scroll down, the skin pack stops loading, but the skins do not appear. I tried pressing the "+" button and it did nothing (Just like when the world failed to sync its user data, the world would not be playable). Is there a way I can resolve this bug or anything you have experienced? Thanks and I hope to see some helpful comments soon.
