Hi @meghan_9144,
I created a custom webpage theme and changed the font for headings in my theme, and I do not see the same behavior. You might want to test in a couple of different browsers and in incognito mode in Chrome https://adobe.ly/3Bnc4Xi . Montserrat is the default, but once you change it to something else, that change should be retained. I wonder if the issue might be caused by a pop-up blocker or some type of browser add-on. Please try test these and see if that helps, Best,
Dave
