Hi Shameera.
I’m new too, but I think I figured this out correctly. You need to make a custom navigation under Appearance > Menus. And under my theme options, there is an area that says Main Navigation with choices for Display Categories, Display Pages, Display Both or Custom. Select Custom and then from the drop-down, choose the Custom Menu you created. I didn’t choose a Home link in my custom Nav, so that worked for me. Hope that helps!? Good luck.
