So I’ve had a look at the theme you linked to and I used the exampleSite folder they included. I am unable to replicate your issue. Outside of one sample post, I don’t see “Docs” referenced anywhere in the theme.
This means that something in your site or in changes you made or in your configuration is triggering this behaviour.
We cannot help you if we cannot replicate your issue.
