Where are the missing Kimojis?

Why have some of the kimojis and gifs disappeared? They were here one day, and when I looked for them the next they were gone. I bought the expansion packs, and now I dont see any of the kimojis I purchased. And whats up with us no longer being able to change the skin tone of the kimojis?
