Issue
Editing the Header Theme options from Front > Header does not reflect in the Header of the website.
Solution
The most common reason why Header Theme options are not reflected in your website’s page is that it may have a Custom Header. You can find out if a page has a Custom Header assigned or not from Front Editor Options available at the top right corner of your Gutenberg Editor.
If your page has a Custom Header assigned, then to customize the Header, you’ll have to navigate to the Static Content that acts as a Custom Header and edit the Front Header Gutenberg Blog to customize.
