Permalink not working

Hi,
I’ve somehow screwed up a permalink.
I created this page: https://staging.christopherbabson.com/personal-development-self-help-life-skills-courses/

That page is just fine. But I later used this template and created a new page, deleting most of the data in the original page. I changed the url to https://staging.christopherbabson.com/seminars-workshops-classes-leadership-skills-development-training-2/

This IS the url that shows up in the main backend page when I open it. However, when I paste that link into a window and hit enter, the original page with the slug “/personal-development-self-help-life-skills-courses/” opens, rather than the page with the slug “/seminars-workshops-classes-leadership-skills-development-training-2/”

I’ve clicked around in Forums, in WordPress instructions and online in general and can’t find any useful information. I know this has to be an easy fix, but it’s somehow evading me.

Thanks!

Chris
