New domain and website wont sync together

I recently registered www.healy-conlon.com 
I started to make a homepage on sitebuilder and published it but it will not display, I have tried numerous times to point the domain to the page i created but it wont display, I have noticed when I try to point the domain to the page, the homestead page says homesteadcloud.com instead of just homestead.com, please see images attached
Thanks
