Emoji app keeps saying I have a notification?

I've got the Emoji app on both my iPhone and iPad, but on my iPad it has the little red bubble on the top corner saying I have one notification. I go into the app to try and find what it is that's causing it to have the little red bubble. I can't figure it out and it's driving me nuts because I want the red bubble to go away. I already tried deleting the app and re-downloading it, but that didn't work it still has the red notification bubble on the corner. It doesn't show up on my iPhone, though. Just my iPad. Is this happening to anyone else? How can I get rid of the red bubble, it's seriously driving me up the wall that I can't figure out how to get rid of it.

Hmm it could just be an Apple glitch but another thought could be it wants to update or something?
