KordingLab.github.io | Jekyll page for Kording lab webpage | Theme library

The navigation buttons on a GitHub hosted website don't take me to the page, and I am unsure how to fix it.

I am very new to GitHub, but am looking to make a webpage for the lab I work in. I found an existing lab webpage (https://github.com/KordingLab/KordingLab.github.io) that allows you to make forks and edit it for your own purposes, which was a great base. I've since changed the repository name but now when I load the page, the navigation buttons don't go to the pages automatically. My website name is myusername.github.io/repository, while when I click the "people" page navigation button, it tries to go to myusername.github.io/people which doesn't exist.

I can manually type in myusername.github.io/repository/people, and the page will come out. Obviously along the way of changing in my teams name while editing, I have messed this up a bit.

The outlay of the original website is kordinglab.com/people, which doesn't include the repository name which is why I think it won't navigate to include the repository. I've had a look through the code, but as I am a bit inexperienced, I can't find how to change it, or where it is controlled.

How can I fix it so the nav buttons actually go to the pages?

https://github.com/KordingLab/KordingLab.github.io provides all the code used in the original and working version. I would be more specific if I knew which file I was looking for, sorry.
