Namespace export; error importing to fresh cluster

In a cluster I exported the namespaces, and then destroyed the entire cluster along with all docker containers to simulate a full restore.

Upon building a new instance of Rancher 2.x and importing the namespaces, I get the error: object has been modified

UI log:

ImportYaml Error

Update: Where are the configuration for storing the Projects/Namespaces located? I thought everything should have been in /var/lib/rancher
