Hi,
Do you mean that you can see the Navigation settings link in Site settings page, but the heads and links are not showing up in the Navigation setting page?
If so, you can try to deactivate publishing feature and activate it again to see whether it fixes this issue.
If I have any misunderstanding, please feel free to point it out.
Thanks,
