Theme Settings are not saving globally

When I first open the Upfront editor, it shows the Home page. I then go into the Theme Settings and switched the font for all of my headings and saved. Then when I go to another page within the Upfront editor, those changes are not displaying. So I go back into the Theme Settings and change all the fonts once again, but when I go to yet another page the new fonts are not displaying on the page nor are they selected within the settings.

Are Theme Settings now per page? How do I change fonts for headings globally?
