In WSO2 Identity Server, once tenants are created from the management console UI, they cannot be deleted from the management console. To delete the tenants, you can use RemoteTenantManagerService and restart the server.

The issue when recreating deleted tenant was caused due to a cache entry and persisted configurations that won't get removed when deleting the tenant through the admin service. Once you restart the server, the cache will be cleared. Then you can create a tenant with the same domain name.

There is a git issue to track this and please refer to the issue for further information.
