Bookmark links on One Page Layout

Hi and I hope you can help. Love the theme, but having an odd little problem.

I’ve set up a One Page template and have used the Page Builder to create different sections – including One Page sections.

I’ve added those sections’ IDs (bookmarks) as links in the One Page menu.

When you visit the site and click the menu item, it scrolls you to the BOTTOM of the One Page section and not to the TOP.

Weird, eh?

Is there something I can do to remedy this or some CSS that I need to add?

Thanks for any help you can offer.
