List numbers not being shown


I am using this template:

Now, I want to use a list with numbers shown on the left side. Exactly what’s being shown here: List | Webflow University

However, adding a list in that template doesn’t show the number, whatever I do or select.

It must be something deep inside the template. How can I make the numbers being shown?
Thanks a lot in advance! I spent 2 hours on it without a solution yet.

Hi people! I am also including the read-only link and hope that anyone can help out with my problem! Thanks!!
