'My Book Table' styling problems

Hey there! I've been trying to use the 'My Book Table' plug-in but have been experiencing some problems with the overall style of the page. For reference, I'm using the Divi theme. I created a separate 'Book' page and added some design elements (a banner image, some background colors, etc.)​. ​When I got that to look the way I wanted it to be, I went into the​ settings of  'My Book Table' and selected that page to be the one the plug-in used to display the book table. 

Unfortunately, it seems to override all of my previous styling. Even worse, it won't allow me to use the Divi builder to fix the styling after the fact. Has anyone else run into this problem, and is there any way to fix it? Or can the book table page only have a plain white background and no additional stylized elements?
