Thank you for using our theme!
Do you change the page content or header layout and have issues with the changes?
If you have issues with the home page header changes then it’s related to the multiple headers option. Go to Theme Options > Header builder > Multiple headers > remove home page header or edit it in addition to the default header that you have to apply changes https://youtu.be/BpeXfzNwkOc
