Hi there Mark, I was also struggling with the same issue since I bought Generatepress 24 hours ago, I followed all instructions but the missing issue required was to go to the individual page (eg home page or about page) where you want to merge page header and primary nav (i.e transparent header) . Click on ‘edit page’ and scroll down to the bottom of the page. You will see options to tweak sidebars, page builder container, footer widgets etc. Choose the option ‘page header’, then you will get a drop down with all the headers you have created. Choose the header you want and publish/update and you will now see your transparent/merged page header and navigation. I am just excited to share because I was struggling with the same issue…hope it helps. Thanks
