Why is Keynote taking up over 60GB of storage on my MacBook?

I always like to have a clear out from my storage. I like Keynote, I use it for presentations. But for some reason, it's taking up over 60GB of storage. When I delete it and reinstall it, it's still that size. I just don't understand why it's taking up so much space when Pages and Numbers take up less than a gigabyte.
