Remove extra Page

Hello, trusting you are well. I am fairly new to WordPress. However, have created a 4 page website from Astra Starter template using Elementor(free not pro) to edit. There seems to be an extra page on the live website that is not visible in the backend. I’m unable to edit it with Elementor or in WordPress. Please advise on how I can delete it?
