Home Page Updating and "Preview" Not working

I'm hosting on WPEngine. When a page is set as the home page and I make an edit to it and click "Preview" the changes do not display. Only if a page is not set as home page am I able to see changes before I publish. 

The hosting company says its specific to the theme...and I'm not sure if there is a setting to fix this in muffin options?

I'm using WordPress 5.2.2
