Theme unit test menu issue

Hello,
I have a question regarding theme unit test.
Whenever I import data, 5 menus are being created, the issue is that all menus are empty. And I can’t achieve menu structure that review team has.
One of soft-reject reasons was a problem with submenu, bu when I build testing menu by myself, everything is okay, so I guess there is a issue with import.
How can I import menu structure ?

Can you provide a link to the menus that aren’t working, also a link to the import log file?
Maybe the user importing doesn’t have the right permissions, maybe the menus are not assigned to the right menu locations…

Without some more details it’s not simple to figure out what happens.
