Hello jfculhane,
From our understanding the main problem of your is that when you select front page, the Header section didn’t display, we have fixed that issue for you. Now when you assigned the front page via Settings -> Reading Settings, the header image won’t disappear. Please update your Education Base theme to latest version and let us know if this fixed your problem.
Also you can change the height of the Header Section, Go to Appearance => Customize => Header Options => Header Image , there is option to increase/decrease height of Header section.
@jfculhane, if you have further any problem or query let us know also we kindly hope you will upgrade your rating and review here 🙂
Best Regards
Acme Themes
