I'd add the following in the Customization > Head > css style box. 100px; is just an estimate.
.header .menu-dropdown {
top: 100px;
}
It looks like your logo does not comply with DaVinci size requirements (190px x 50px), that must be causing the issue.I have an issue with the menu overlapping the site logo.
Is there a way to reposition it lower?
I have tried the css route only to find out we can't edit the css without breaking everything.
