Andreessen Theme Pdf Export

All my textboxes (for examples, exercises, and learning objectives). Go much further across the page then the rest of the text in my pdf exports. Using the default margins, the textboxes actually touch the side of the page. I was able to fix it a little but not much. Also the title of these textboxes is often an orphan. I adjusted the orphan setting to 2, but am still struggling. Any advice would be helpful. !
