Website edit part of website help

Hello,

I want to edit the area are of the site on homepage under the main slider where boat selector is present.

I edited all boats on the site to have Cote D’Azur as location, but there appears in the selector other Locations.
When I try to edit the Page that is selected as homepage, the boat selector part do not appear on the editor. How is this possible?

Do you have any idea how to edit the Boat Selector on the homepage?

I bought the theme from themeforest, but they told me they no longer want to offer support for me. They also refunded me with no explanation.

The page I need help with: [log in to see the link]
