Upfront Luke & Sara Theme - big Database

Hi,
i built with the Upfront theme a page. By export the database for my live server i got a very big database. The sql file i can not use with 90MB. Is the problem the theme and editor? All other WP database exports are only 550kb and i do not more this time. Please check the image. The Posts are very big but i have no Posts in WP. It must be the editor from the theme. What kann i do ? Thanks for help. Cheerse
