Hi,
1/ We've said about this issue here - you need go to Dashboard > Settings > Reading > and make your config look like this image.
2/ Please go to Appearance > Menus > create or select a menu for your main navigation > scroll down and check to "Primary Menu"
If it still doesn't work, let's deactivate all plugins ( except plugins come from the theme ) and try it again. After it work, let's enable each plugin to check what's plugin caused this issue.
Best Regards,
