Troubleshooting Overlay Heading and Background Issues with Header 83 in Webflow

I'm trying to use Header 83 in a webflow site and the overlayed heading/buttons just won't show up on the front end for some reason. I've tried checking the interaction settings, z index, opacity etc but nothing seems to fix it. I've also tried re-copying and pasting the component from the library in several times but same issue. I'm also noticing background overlay blocks also aren't showing properly. Any ideas?
