Main Domain Different From Mine

hello, i purchased a domain from, but when i go to cPanel on Main Domain it shows me this: , while when i registered i used only the domain i purchased. How to fix this please and thank you!

Also when i try to install Wordpress from Softaculous it shows me a completely different domain : and i can’t change to mine, why is this happening if someone could explain would really appreciate it since im very new to these things and Thanks again!

Every account has main domain that according to your account. Actually I know only one thing where it’s useful - pointing your domain to IF server with CNAME DNS record

upd: softaculous broken for all, just wait
