How to adjust anchor stroll point

Side question, how can I set the anchor stroll to display the TOP of Page Section, My nav is set to “fixed” not “sticky” as other forums suggest might be the issue. As you can see my nav bar is cutting off the top. of the page section header.

Also, see the blue outline highlighting the page section that you jump-to? I would like to prevent that from happening.
