Removing old domains from SSL / DNS, Error creating new order

On [canliscommunitycollege.netlify.app] (default domain) I am having problems getting my ssl to renew and I believe it is because of stale domains. I have a CNAME for community.canlis.com on dreamhost pointed to the default domain. How can I remove these? I have flushed the DNS cache,and also removed them from dreamhost where the domain is hosted.

I’m looking for the ssl to renew for community.canlis.com which is the primary domain.

Here is what I am currently getting with SSL. I don’t need any of those domains shown in the image

I believe I resolved the issue by deleting the domain and re-adding it. Then only the CNAME of community.cnalis.com showed up and the lets encrypt cert was successful.

It’s taking some time to populate around however. I can see the site while others get the dreaded site is insecure error
