My navbar has each tabs three times. I tried to “Reset All” in the Import/Export Dummy Text tab and then Add the Construction theme. I did this twice and the site reset, but the tabs did not remove.
The dummy data is stored in the database. So unless you have cleaned up the database before the second (and then third) import, some of them will be duplicated. All you have to do is go to Appearance > Menus and delete the duplicates.
