Font control within parent and child themes

I have an issue with font control. I have FrameMarket installed and regardless of the child theme being used, on my home page I still see the default FrameMarket styling (at least that's what I think it is) for both the store item headers and descriptions. However, when I click on an item, the correct child theme styles show up on the page for that item. Can someone explain what's going on and how I can override the parent theme styling on the home page? Many thanks in advance!
