Page layout – Slider element not sitting at top of content area

This I’m sure is a super easy one but I’ve been searching for the settings all day.

I have one element so far on my home page which is a full width ‘Layer Slider WP’ element with images. This is currently leaving a margin at the top and bottom where I can see the colour of my main content area.

How can I make the image slider sit at the top of the page tight against the menu header?

Slider ‘Layout’ settings are at ‘full-width’, Sliders ‘Size’ settings are set to auto. Surely it’s some combination of these settings?

Thanks
