Ubermenu, not like demo after import.

Hello team,
I made a search on the forum about ubermenu to look like demo. But most of them end with you offering direct support via logins.
I am building on localhost(with vHost) so I hope you can walk me through it.

I installed all plugins first, including ubermenu, then did the import, then
– Integration -> Automatic Integration Theme Location -> Tick “Header menu”.
– Submenus -> Bound Submenu To -> Unbounded.

But my menu looks like attached.
