Hello kwwinter,
Thank you so much for using our support forum for the query. First check the header ads options available on the theme from Appearance > Customize > Header Options > Header Image and check all the available options. If there was the ads code, it may be blocked by the ad blocker. So check is there any ad blocker installed or not?
If the problem is not solved again, let us know.
Regards
Acme Supports
