When adding a new page, a post is created automatically?

Hi, so I am setting up a booking plugin for a client, (Booki) I went to add a new page to insert the shortcode and oddly, it automatically creates a post, shows new post submitted by"username" x minutes ago, and there's an author section, place to leave comments its as if I literally made a blog post, yet I'm in the add a new page section :S really confused.
