Let’s handle one issue at a time.
The home page hero section can be edited under Appearance > Elements:

That being said, I would actually recommend removing that header element, then just rebuild the section as the first section in your home page content using GenerateBlocks as the other sections on the home page.
Let me know if this makes sense.
This site is a bit out of date and I’ll be rebuilding it so it’s more intuitive but let me know if you need more info in the mean time 🙂
