Hi,

Yeah, it caused by the sticky menu override it.

The solution here is use an anchor links above your heading.

Example:

You has an anchor like this:

<h3 id="xxx">content here</h3>

You should use an empty anchor above this heading, like this:

<span id="xxx"></span>
<h3>content here</h3>

It doesn't affect anything to your site, but it make your anchor display better more.

You can put the <span id="xxx"></span> anywhere inside your content because it doesn't affect anything.

Best Regards,
