There seems to be an unexpected behavior with the menu items that have subitems. Regardless of whether I choose an icon or leave the selection empty, an icon is added and there is no way to disable it without using CSS.
I doubt it is intentional because usually bricks is good about not overwriting design choices and settings with updates.
Another issue is with font size of dropdown items. Even though the font size is set to 14px in bricks settings, it reverted to body size (just for items with dropdowns) – this was fixed after resaving the header template.
