it seems that latest version of URE pro (4.34) conflicts with Max Mega Menu (https://wordpress.org/plugins/megamenu/)
After updating to 4.34 one (arbitrary) submenu level is shown as main menu bar (sublevel was formerly a flyout of an upper level), rest disappeared, and another Max Mega Menu (used in a widget area) disappeared compeletely.
After reverting back to URE-pro 4.33 all Mega Menus are working correct again and all issues are gone. Maybe it is an issue concerning the new Front-end-menu-add-on (Not logged-in and logged-in users with selected roles)
Any help is much appreciated!

Thanks for this information. It would be good to look on a screenshot of broken menu (use some public resource or send it directly to my support email). I will try to reproduce and isolate the issue.
Can you test if this problem disappear if you turn Off ‘Front-end menu access add-on’ with version 4.34?
