Blog GitHub pages appears with an additional extension

My blog is made on github pages and in Google the domain is added .atlaq.com/ like this
https://noemioocc.github.io.atlaq.com/

What is https://atlaq.com/ And why does it have information from my blog and how do I stop it from showing my information?

I want to delete my information from https://noemioocc.github.io.atlaq.com/ because the name of the site and the description are incorrect

I already updated the blog information in github pages a few months ago and it still appears incorrectly in https://noemioocc.github.io.atlaq.com/ What file should I delete so that https://noemioocc.github.io.atlaq.com/ with that additional .atlaq.com extension ceased to exist

please help me and thank you

I hope I know how to make atlaq.com stop showing information about my blog
