Main Navigation Not Showing On Site After Using Elementor Menu

Hi! I'm currently having a problem with my site...

The main navigation is not being displayed. I used the menu widget from Elementor, along with the plugin Header & Footer Elementor to display it easily. In the customizer I selected "without navigation".

But now I want the GP navigation to be displayed as I've found the Elementor's widget to be not too responsive. So I delete the Header & Footer Elementor, so that deactivate the menu from elementor, went to customizer and selected below header position for the main navigation, but nothing is being displayed.

I've already cleared cache but the problem remains, any thoughts on what should I do to fix this?
