Foreman node caching

Hi

I am having a strange issue whereby I deleted a node in Foreman but the
node yaml still exists:

https://foreman/node/dbp142r.prod.something.net?format=yml

When I try and add and rebuild this node, it is built with the settings
above. How do I remove this from the system. I made sure it was not in the
hosts table in the DB.

Many thanks.
