Can’t get single staff page to work

I tried this:https://abcfolio.com/wordpress-plugin-staff-list/documentation/create-single-page/

Then this:?https://abcfolio.com/wordpress-plugin-staff-list/documentation/links-to-single-page/

I click on the “View Bio” link and the URL changes, but the page is just reloading.

Thanks!
