Duplicated and updated page; renamed to original, now not directing properly

I duplicated “mysite.com/page-one”, which resulted in “mysite.com/page-one -copy”.
I made all changes to the “/page-one -copy” and then renamed it to “/page-one”.
I renamed the original /page-one to “/page-one-2”.

The problem now is that all of the links from other pages coming into to the new “/page-one” are pointing to /page-one-2, instead of the newly edited and renamed one. I have changed the slug name on the pages to match the respective page and my permalink is set correctly to “https://mysite.com/%postname%/. I’ve also gone to Appearance>Menus to see if anything was amiss. I removed the page link and reloaded it as a precaution. Nothing works. I’m at a loss. Any ideas as to what step(s) I might be missing or doing wrong?

Thanks for the help.
