In the backend, go to -> Display -> Content menu, select and open the menu with ID 336.
In the left pane ("Display"), near the bottom, you have "Associated modules", and for some reason there is a module associated (one with ID 150, but you can only see its name, not the number there), which is the one displaying below the menu product listing, but which you obviously don't want.
So then, click onto the button. In the popup, find the module (which is set to "Yes"), set it to "No", and save with the "Ok" button in the upper right corner of the popup.
Back in the main window, click "Save" in the upper toolbar, then check your site again. Should be good.
