Thank you for reaching out, and I'm sorry for the issues you are running into.
I've spoken with our product management team and got this reply:
This was an intentional design choice to prevent the menus from being cluttered. We've recognized this poses problems for custom layouts and are exploring solutions. We apologize for the inconvenience this may have caused you.
Hope that helps explain the situation.
Thanks
