Why are my step details not visible from ./courses/1 but only from .courses/1/t1 or /t2? They are visible in admin.

For the Django Forms video Quiz Model, I followed all of the steps carefully. I've been working the project locally on my own computer rather than in workspaces. I went back through the whole video to make sure I didn't miss any changes.

From the Courses page, if I click on Python Basics, I get the same view as I did before the changes in this video, which is to say, it just gives the course description, not the steps. If I go into admin, I can see the steps that I had previously added, and clicking 'view on site' leads me to a page that has the url ./courses/1/t1, which makes sense to me, given the t added to the regex in the video, but in the video, it is shown that the steps should be visible on a page which doesn't have the t in the url.

I can attach my code if I need to, but I've triple checked that it matches up with the video.
