Site is stuck on We're provisioning a certificate for your site

Can someone help me understand what I am doing wrong, we are trying to set the subdomain as the primary but keep getting We’re provisioning a certificate for your site, you cannot change custom domains until that process completes.

We are trying set up a subdomains for emtexas.com which is hosted else where, we do not want to use that domain at all and cannot point that domain over since it is a live site but just subdomain but can’t remove the primary domain or change which subdomain is primary. We created three subdomains (learn-more-lp.emtexas.com, concierge-medicine-lp.emtexas.com, and executive-medicine-ip.emtexas.com) with their CNAMEs configured, but when you attempt to set one as primary, you get a message that certificate provisioning is in progress and blocking the change. We might have accidentally added emtexas.com to the project by accident but can’t remove it.

I would like help removing emtexas and the www (which you accidentally added and is hosted elsewhere), and want to either use emtexas.netlify.app or any of the other as the primary domain instead.
