Custom Domain not loading correct site

Trying to launch our site on a custom domain and I am totally stumped.

The issue:
(1) correctly maps to the Webflow site
(2) maps to the old site hosted at Siteground

I would like both addresses to point to the Webflow site.

A and CNAME records are added to DNS Zone on Siteground and the status for both addresses show as connected on the Webflow hosting tab.

What am I missing here?
