Not able to change the email from the default value of [email protected]

I created a blog site on www.remarpro.com. By mistake, I let the email address to be the default value provided, which was [email protected]. I have no connection to this [email protected]. The site is up and running. Whenever I change the email address to my actual email [email protected] in the profile section at https://13.232.249.167/wp-admin/users.php, the page reflects the change as

"There is a pending change of your email to [email protected]"

No email ever comes to me. How can I fix this? It looks like the email [email protected] is the final authority of my website, not me.
