I created a new page and I can't access it. I keep getting the 404 error

Hi,
Yesterday, I’ve migrated a website to wpengine.com servers. Today, I tried to add a new page to the website and I’ve seen that even though the page exists in the dashboard, I can’t access it from the browser. I can’t access it from the “View Page” tab or by inputting the url in the url bar of the browser.

More details:
I basically want to change the https://www.scurri.co.uk/features-2/
with https://www.scurri.co.uk/features/ . But if I change the url, I can’t access the page anymore.

Now I’ve seen that when I try to access https://www.scurri.co.uk/features/ I’m beeing redirected to https://www.scurri.co.uk/features-2/

If anyone has any idea about what’s happening please let me know. I searched everywhere for an answer, but I can’t seem to be able to find one.
