Owl Carousel can't be put in a post?

So, I made an owl carousel and put it into one of my posts to serve as a gallery of screenshots of a game. When I published it, it made a mess of my post.

Here is a photo of the “bug” using the carousel on a post:

Here is without the carousel:

I don’t know what’s wrong. Maybe it’s a widget bug?
