bar menu link to homepage widget

I’ve made the links work but only if I put the name of the widget on the link. for example it works when I put https://www.ilustraeris.com/#shapely_home_parallax-12
but it doesn’t look professional and I would like it to be https://www.ilustraeris.com/#about instead of the previous one. I have tried the suggested solutions in this forum but still not working. https://colorlibsupport.com/t/how-to-create-menus/

Can anyone please help me? I have been waiting for an answer for 6 days and this is the only thing that is keeping me from putting my website live. And been trying to find solutions but to no avail.

Thank you,
Eri
