With Helix Ultimate 2.x vs 1.x there is now a class (justify-content-end) that is added to our menus that are shown as headers and it's off setting the menus to the right so much that they won't show completely (part shows off screen even on super wide screens).
The problem is in plugins/system/helixultimate/layouts/frontend/modules.php with the following line:
$columnClass .= $isHeader && $options->name === 'menu' ? ' justify-content-end' : '';
This justify-content-end class is the problematic one. In 1.x the classes assigned were simply sp-column but now it's : sp-column d-flex align-items-center justify-content-end. All classes are OK except justify-content-end.
I have no clue on how to prevent that behaviour so for now I directly commented that line out but it's not ideal (updates will override my fix).
Oh also. Helix Ultimate 2.x with PageBuilder 3.7.9 it's now impossible to modify the Styles (Extensions -> Templates -> Styles), when the big green button "Template Options" is clicked nothing happens.
Before you ask, no I won't provide credentials to access the websites we host.
