DNS Cache issues -> Our custom domain keeps pulling data from an older Apidog project

We have these 2 projects published:

Old: https://rd9ucd81nt.apidog.io/
New: https://67d7n1uzn0.apidog.io/

This domain

has been change to poing to the CNAME of the new as can be seen here:

But for some reason when I go to the vulcan-forge-docs.alphaledger.com it still pulls the docs from the old. The way you can tell the difference is to go to:
vulcan-forge-docs.alphaledger.com
and search for svmCluster.

The new docs have that URL params. The old project does not.

Do you know what is going on?

I forgot to mentioned, I cleared the DNS cache on my machine.
