Thanks for reaching out to Cloudflare Community! Sorry to read that you’re experiencing difficulties.
I’ve spotted that your DNS records were configured\imported incorrectly, as the domain suffix was duplicated on all records. This in turn caused the apparent DNS propagation issue.
For instance, instead of mysupport.cfch.com.au, you have mysupport.cfch.com.au.cfch.com.au. Perhaps best to bulk remove all DNS records and start over fresh?
I hope this information was useful, let us know if we can further assist you in this matter!
