With Helix Ultimate 2.0, the menu in the header which used to span the entire width of the layout now floats right on all pages. When I inspect the page, the style that seems to cause this problem is the style for

<nav class="sp-megamenu-wrapper d-flex" role="navigation">

.d-flex { display: flex!important;}

If I uncheck the .d-flex style, the menu returns to the way I designed it. Also, it shows the hamburger in all layouts, and I only want that to show up in mobile devices.

There are other anomalies as well. On the home page, there's a grid of boxes that are no longer spacing properly horizontally. Also, the client notices that photos are not completely filling up the boxes in which they are placed. You can see the problem here:

Needless to say, this was an unexpected and unwanted change, and I need guidance on how to restore my site to the way it was designed. Changing settings in the tempate options doesn't seem to work.

Thanks.
