Hello, @ranawebdesign,
1. I have checked your site and tested it. It appears to be working properly, as you have described. I have recorded a video for you to watch for further reference: https://streamable.com/7fyeb7.
2. To adjust the margins, navigate to the Dashboard >> XSTORE >> Theme Settings >> Header Builder >> and adjust the margin settings from the bottom, as seen in this image: https://postimg.cc/30xbKGrc. Once you have saved the settings, please clear your browser cache and check back on your site.
We hope this helps.
Best Regards, 8Theme’s Team
