Why does the hamburger menu appear on the desktop AND regular mega menu missing ?

Thank you.

Try re-saving both forms.

Check out updating.

Also be sure to read the entire docs:
/admin/help/ultimenu

Let me know?

Haven't touch anything since yesterday, and it works now. Maybe the cron do the job. Thank you gausarts.
